Cornell-led Team Creates Gallium Nitride Power Diode
| Cornell UniversityEstimated reading time: 3 minutes
The team used a couple of indicators to determine the defect level in the GaN diode, including “diode ideality factor” as measured by the Shockley-Read-Hall recombination lifetime. The SRH lifetime is the average time it takes positively and negatively charged particles to move around before recombining at defects, which creates inefficiency.
