Crystallinity Evolution of MOCVD-Grown -GaO Films Probed by In Situ HT-XRD under Different Reactor Heights
Imteaz Rahaman, Botong Li, Bobby G. Duersch +3
The crystallinity of -GaO thin films grown by metal-organic chemical vapor deposition (MOCVD) is strongly influenced by reactor design and the resulting growth environm…
Dosimetry for Proton Therapy Using a β-GaO Metal-Semiconductor-Metal Detector with Low-Noise Amplification
Hunter D. Ellis, Ajayvarman Mallapillai, Jared Miller +4
Intensity-modulated proton therapy (IMPT) employs proton radiation rather than conventional X-rays to treat cancerous tumors. This approach offers significant advantages by minimiz…
Control of Extraordinary Optical Transmission in Resonant Terahertz Gratings via Lateral Depletion in an AlGaN-GaN Heterostructure
Geofrey Nyabere, Hunter Ellis, Miguel Gomez +7
Periodic metallic gratings on substrates can support a range of electromagnetic modes, such as leaky waveguide, guided-resonant, and Fabry-Perot (FP) cavity modes, which can strong…
In situ XRD Study of Strain Evolution in AlGaN/GaN HEMT at High Temperatures up to 1000 °C
Botong Li, Bobby G. Duersch, Hunter Ellis +6
The thermal stability and structural evolution of a GaN high-electron-mobility transistor (HEMT) heterostructure grown on a Si (111) substrate were investigated using in situ high-…
In situ Study of p-NiO Film Quality at High Temperatures up to 1100 deg C
Hunter Ellis, Bobby G. Duersch, Botong Li +4
NiO is a promising p-type material for photovoltaics and power electronics, but its temperature limits remain unclear. Using in situ high-temperature X-ray diffraction (HT-XRD) fro…
