A big deal for China
It marks the highest stable energy electrons can have. It determines whether and how easily a semiconductor conducts electricity. By introducing specific impurities and increasing gate voltage, they minimized dislocations in GaN fabrication.
“Traditional strategies to avoid defects include using different substrates and adjusting crystallization temperatures, but these approaches only address the symptoms, not the cause,” said Professor Huang Bing with the Beijing Computational Science Research Centre on Tuesday.
