Congratulations to Department of Electrical Engineering Faculty members, Professor Zachary Holman and Professor Chao Wang, for winning the National Science Foundation (NSF) career awards Professor Zachary Holman’s award is titled, “Transparent, Passivating, and carrier-selective heterojunction contacts for silicon and cadmium Telluride solar cells”. It funds research to better understand and augment the behavior of solar cell electrical contacts to increase the efficiency of solar energy conversion. His work could achieve 10 to 15 percent more efficient than the ones today, which increase the percentage of U.S. energy generated by solar to 17 percent by 2030.     Professor Chao Wang’s award is titled, “Integrated optofluidic chips towards label-free detection of exosomal microRNA biomarkers”. The ExoMiRChip developed by Professor Wang, is an intergrated fluidic device on a silicon chip to improve the capabilities of lliquid biopsy to diagnose cancer and infectious Neurodegenerative diseases. The project could help to accelerate the diagnosis progress from weeks down to hours with greater...

Professor Yong-Hang Zhang was elected as the chair for both International Conference and the North American Conference on MBE Professor Yong-Hang Zhang, the director of Center for Photonics Innovation, was elected as the chair of the advisory boards for both the International Conference (IC MBE) and the North American Conference on MBE (NAMBE) in recognition of his outstanding leadership, contributions and achievements in the area of molecular beam epitaxy and its applications. The International Conference on molecular beam epitaxy (ICMBE) is a biannual conference and has over 40 years history.  The 20th conference took place in Shanghai, China, and it provided a prominent international forum for reporting new developments in the areas of fundamental and applied molecular beam epitaxy research, including advances in the technique, synthesis of new materials, discovery of new physical properties, formation of novel heterostructures, and the development of innovative devices. The 34th North American Conference on MBE (NAMBE) was held in Banff, Canada. NAMBE is an annual conference, which provides a prominent North American forum for reporting scientific and technological developments in Molecular Beam Epitaxy research. It is worth mentioning that the ASU MBE research group, led by Professor Yong-Hang Zhang, has a total of three students who received 2 Best Student Presentation Awards and 1 Best Student Poster Award in past year’s MBE conferences. Congratulations to Professor Zhang, and to his group for their excellent work!   ASU MBE Optoelectronics Group: https://mbe.engineering.asu.edu/ Official Link for ICMBE: http://mbe2018.csp.escience.cn/dct/page/1 Official Link for...

MATERIALS SCIENCE DOCTORAL STUDENT WINS OUTSTANDING STUDENT MBE AWARD IN CHINA Calli Campbell, a doctoral student studying department of materials science and engineering from Ira A. Fulton school of engineering, won the Outstanding Student MBE Award for her oral presentation at the 20th International Conference on Molecular Beam Epitaxy in Shanghai, China. Campbell earned one of the two Outstanding Student awards out of 135 student contributed presentations in recognition of the quality of her research and presentation. Her presentation, “MBE growth and band-offset measurement of CdTe/InSb(002) heterovalent interface,” discussed using X-ray photoelectronic spectroscopy to investigate the junction between MBE-grown crystalline compounds cadmium telluride and indium antimonide which often used in the applications like solar cells, lasers and multi-color photodetectors. She appreciates the support of her co-authors Dr. Xingye Wang and Professor Robert Nemanich and her advisor Yong-Hang Zhang, under whom she is a graduate research assistant in electrical, computer and energy engineering. “I am incredibly honored since this is a community full of people I learn from and look up to,”“It is nice to know that our work at ASU is being well-received by the global MBE community.” said Campbell.   Article...

Dr. Chao Wang and collaborator Dr. Yu Yao are supported by NSF to develop an ultracompact on-chip integrated metasurface polarimetric imager It is no exaggeration to say that the development of imaging sensors has made profound impact on our life, from a smartphone camera to the most advanced medical imaging equipment, and even to space exploration. Detecting light polarization has been proven to be essential for various applications such as biomedical diagnostics, remote sensing, target detection and astronomy. Yet, despite the fact that the sensitivity, speed, pixel density and color range of image sensors have been continuously improved, the capability of full-polarization imaging, hasn’t been realized on monolithically integrated sensors. This project is to develop a chip-integrated imaging sensor array, or in another word, polarimetric imaging array, to detect not only light intensity and color but also the complete polarization state of light. Such a compact system can be further incorporated into many portable systems for clinic diagnostics, real time environmental monitoring network, or a smartphone polarimeter for field study and research. By integrating research and education, the project is aimed to inspire and cultivate the next-generation of scientists and engineers in nanophotonics and nanotechnology to address grand challenges in health, security, environmental issues and space exploration.

Dr. Yu Yao and collaborators Dr. Sefaattin Tongay and Dr. Chao Wang are supported by NSF to explore new strategies to integrate quantum emitter arrays in 2D artificial superlattices with nanophotonic structures towards room temperature quantum logic operations. Two-dimensional (2D) crystals are a new class of materials that measure only a few nanometers in thickness. Recent studies have shown that these materials offer unique advantages over other known materials, and that they hold the potential to make a large impact in new-generation electronics, energy conversion, and storage applications. When these 2D crystals are stacked onto each other they form a material known as a 2D Moire superlattice, which possesses an unusual physical properties that may enable quantum computation. Such materials could revolutionize current information technologies. This research aims to reach a fundamental understanding of the optical behavior of 2D Moire superlattices using advanced optical measurement techniques, as well as develop state-of-the-art fabrication techniques to create nanoscale devices for manipulation of quantum information. Particularly, this research explores the quantum optics of Moire quantum emitters (Moire-QEs) as single-photon emitters and their integration with Fano-dielectric metacavities, allowing manipulation of coherent states in quantum logic operations. The research activities have significant impact on training of next-generation researchers. Doctoral and master students, as well as undergraduates conduct all the necessary experiments, participating in hands-on research activities.

Professor Yuji Zhao Won $1.5MM DOE ARPAe PNDIODE Program The ASU team led by professor Yuji Zhao, assistant professor of electrical and computer engineering in Ira A. Fulton Schools of Engineering, won the $1.5MM grants from ARPAe PNDIODE Program of Department of Energy. The team proposes a comprehensive research program to advance fundamental knowledge in the selective area growth of GaN materials in order to achieve selective area doping, leading to the development of high-performance GaN vertical power transistors. The team will develop a new fabrication process and determine the opportunities to solve the challenges of selective area growth for doping in GaN materials. The team will also conduct a materials study and investigate several issues related to GaN selective area epitaxial growth. If successful, the project will demonstrate generally usable p-n junctions for vertical GaN power devices that meet PNDIODES program targets.   Official Website Link:...
