Congratulations to Preston Webster for winning the prestigious Young Investigator Award of the NAMBE 2025. Preston is our center alumnus and received his PhD under the supervision of Shane Johnson in very close collaboration with our MBE Optoelectronics Group in a MURI program.  We are very proud of his achievements.

Allison McMinn traveled to Berlin, Germany as a part of a collaboration effort. While at the Paul-Drude Institute (PDI) she assisted with MBE protocols, shadowed leading researchers in MBE and conducted Raman measurements on her narrow-gap semiconductor samples, under the guidance of Senior Research Scientist Dr. Esperanza Luna

Congratulations again to the MBE Optoelectronics Group for another recent paper chosen by Solar RRL as the cover page story. A recent article by the ASU MBE Optoelectronics group has been selected as the cover article in Solar RRL. The paper, titled “Monocrystalline CdSeTe/MgCdTe Double-Heterostructure Solar Cells”, reports monocrystalline CdSeTe/MgCdTe double-heterostructure solar cells with varying Se compositions in the…

Congratulations to the MBE Optoelectronics Group for their recent paper chosen by Solar RRL as a cover page story. A recent article by the ASU MBE Optoelectronics group has been selected as the cover story in Solar RRL. The paper, titled “Interface Fermi-Level Engineering for Selective Hole Extraction Without P-Type Doping in CdTe Solar Cells…

Achieving effective p-type doping remains a major challenge in CdTe, nitrides, and various oxides. The high dopant activation energies in these materials limit the concentration of ionized carriers, thereby impeding device performance. To address this issue, we have developed an innovative approach—interface Fermi-level engineering—using interface states and charge transfer effects to tailor Fermi level without…

ASU MBE Group organized a spring reunion at Evelyn Hallman Park in Tempe on April 12. The event brought together current group members, alumni, and friends from other research groups for a fun and relaxing day outdoors. Everyone enjoyed good food, games, and conversations. In addition to catching up socially, some attendees also discussed their…

We are pleased to congratulate Dr. Xin Qi on the successful defense of his Ph.D. dissertation, entitled “Study of Thin-Film Cd(Se)Te/MgCdTe Double-Heterostructure Solar Cells and Novel Epitaxial Lift-off Techniques.” Dr. Qi will join Texas A&M University as a postdoctoral researcher. We wish him continued success in his academic career and look forward to future collaborations…

We are excited to share that Razine and Allison have been awarded the ARCS Scholarship, a well-known honor that supports top graduate students in science and engineering. This award helps students continue their research by providing funding and recognition for their hard work. With this win, we keep our 15+ year record of receiving this…

On October 23, 2024, Prof. Yong-Hang Zhang presented an invited lecture titled “Antimonide Type-II Superlattices and Heterovalent Integration: From MBE Growth, Materials Physics, to Device Applications” at the University of Michigan. His talk explored advanced concepts in molecular beam epitaxy (MBE), materials physics, and their applications in cutting-edge device technologies. This lecture was part of…

Congratulations to Dr. Tyler McCarthy on his successful Ph.D. defense entitled “Molecular Beam Epitaxial Growth of Group-IV and Heterovalent Structures for Infrared Detectors and Quantum Transport Study”. Tyler will stay in our group to work as a postdoc. We are looking forward to making more progress in the future with Dr. Tyler McCarthy.
