F. (Shadi) Shahedipour-Sandvik received the Bsc degree in physics from University of Tehran-Iran and the PhD degree in experimental solid-state physics from University of Missouri-Columbia in 1992, and 1998, respectively.

From 1998 to 2001, she held a postdoctoral and Research Associate positions in the Departments of Materials Science and Engineering, and Electrical Engineering at Northwestern University, respectively. There, she was the first to report a fully packaged GaN-based photocathode detector for solar-blind applications. In 2001, she joined the College of Nanoscale Science and Engineering at SUNY Polytechnic Institute, where she is currently a Professor of Engineering. Her research focus is on development of understanding of materials characteristics-device performance relationship, enabling improved performance and/or functionality of opto/electronic/sensing devices based on III-nitride material systems. Her current research interests include the theoretical study/simulation, design, fabrication and measurement of Cs-free photocathodes, high power HEMT, photon detectors, and beta(photo)voltaics-based on III-Nitrides. Dr. Shahedipour-Sandvik was appointed the first Presidential Fellow with the Research Foundation for SUNY in 2013, SUNY Provost Fellow in 2012, and was awarded NY Governor’s 2005 Woman of Excellence Award for her professional accomplishment and contribution to the community. She is the current Editor-in-Chief of the Journal of Electronic Materials.

Isra Mahaboob joined Prof.Shahedipour-Sandvik’s lab in spring 2013. Over the course of five years she has successfully conducted advanced research in the area of III-nitride based opto-electronic, power-electronic and sensing devices. She has a Bachelor of Engineering degree in Electrical and Electronics from Visvesvaraya Technological University, India and Master of Science Degree in Nanoscale Engineering from SUNY Albany. She has an industry experience of nearly 6 years as an integrated circuit physical design engineer. A major part of industry experience comprised of working on IO interfaces with Intel on several of their latest designs and processes and on SRAM design with Cypress Semiconductors. Her multidimensional experience and expertise in semiconductor deposition, device design, fabrication, electrical characterization and front-end design of mixed signal complex circuits positions her well to be an impactful asset to research and development of next generation semiconductor materials and devices. Her other interests include hiking, birding, trekking and outdoor adventure.

Projects:

  • Development of high power AlGaN/GaN high electron mobility transistors (HEMTs) using metal organic chemical vapor deposition (MOCVD) technique, including selective area epitaxy (SAE) growth technique for stretchable HEMTs. Processing, fabrication and electrical characterization of HEMTs in challenging stretchable geometric designs.
  • Design, fabrication and characterization of AlGaN/GaN HEMT based biochemical sensor for the detection of chemical species in living cells.
  • Integration of body bias based novel device design technique to control the ON/OFF performance of AlGaN/GaN HEMTs
  • Design and development of HEMT MIS devices.

Hailing from Saratoga Springs, NY, I graduated from Smith College with a BS in Engineering Science and a minor in physics in 2016. During my time at Smith I gained experience through internships at the City of Cohoes, SUNY Polytechnic Institute CNSE, and Schneider Electric. Following graduation from Smith, I joined Prof. Shadi’s group in the summer of 2016 to pursue a PhD in Nanoscale Engineering.

I am passionate about engineering education, and specifically increasing representation of minorities within engineering. Additionally, I have a strong interest in environmental ethics and the impact the semiconductor industry has on the environment. In my free time I enjoy taking ballet class, medieval languages, and strong coffee.

Research Interests

  • MOCVD growth
  • Electrical and structural characterization of materials and devices
  • Device design through polarization engineering
  • Optimization and modification of surfaces and interfaces

I hold a Bachelor of Science in Nanoscale Engineering with a minor in Mathematics from SUNY Polytechnic Institute’s College of Nanoscale Science and Engineering. During the summer of 2015, I joined Dr. Shadi’s group as an undergraduate intern investigating the thermoelectric properties of III – Nitrides. In addition, I worked with the Global Society for Contamination Control during my undergraduate career evaluating the properties of cleanroom consumables. Upon completing my undergraduate studies in the spring of 2017, I stayed with the WBG Optronix group to pursue a PhD in Nanoscale Engineering.

In my free time, I enjoy playing and watching soccer, computer programming, and spending time with friends.

Research Interests

  • MOCVD growth and characterization of III – Nitrides
  • III – Nitrides based power devices

Research Interests

  • Design, fabrication, testing and characterization of 2-DEG High Electron Mobility Transistors (HEMT) devices.
  • Wide band gap semiconductor physics
  • Photoconductive semiconductor switching
  • Nonlinear optics of semiconductors

Biographical Sketch

I have a BS/BA double in Physics and Government from Houston Baptist University, where my capstone project focused on simulation of Planck-length dependence of quantum well depth. I obtained my MS in Electrical Engineering in 2016, where my thesis research focused on measuring and modelling nonlinear optical absorption in GaN and SiC at below- and above-band gap optical energies. Additional post-master's research focused on the development of a pulse-charged, high-gain semi-insulating GaN photoconductive switch. My current work in Dr. Shahedipour-Sandvik's lab concerns fabrication of high electron-mobility transistors (HEMTs), and thermal activation of Mg-doped GaN.​
