Excess Noise in High-Current Diamond Diodes -- Physical Mechanisms and Implications for Reliability Assessment
Subhajit Ghosh, Harshad Surdi, Fariborz Kargar +5
We report results of an investigation of low-frequency excess noise in high-current diamond diodes. It was found that the electronic excess noise of the diamond diodes is dominated…
Low-Frequency Noise Characteristics of GaN Vertical PIN Diodes -- Effects of Current and Temperature
Subhajit Ghosh, Kai Fu, Fariborz Kargar +3
We report low-frequency noise characteristics of vertical GaN PIN diodes, focusing on the effects of the diode design, current and temperature. The as-grown and regrown diodes, wit…
Direct Observation of Acoustic Phonon Confinement in Free-Standing Semiconductor Nanowires
Fariborz Kargar, Bishwajit Debnath, Kakko Joona-Pekko +5
Similar to electron waves, the phonon states in semiconductors can undergo changes induced by external boundaries. Modification of acoustic phonon spectrum in structures with perio…
