Effect of Heat Treatment on Electrical Properlies of GaAs

열처리가 GaAs의 특성에 미치는 영향

Investigation of the electrical properties of GaAs after the heat treatment at various As vapor pressure have been carried out. Hall coefficient mesurments were utilized to study the cause of the effect on the electrical properties, of GaAa by the heat treatment. Various defects possibly created by the heat treatment were discussed. Also, p-n GaAs diodes were fabricated and the I-V characteristic curves were presented.

GaAs을 여러가지 As의 중기압하에서 열처리를 하여 그의 특성이 어떻게 변했는가를 조사하였으며 열처리과정에서 생기는 결함들이 어떤것이며 그의 성질이 어떤것인가를 알아 보았다. 아울러 As GaAs의 P-N 접합을 만들어 그의 P-V 특성을 측정하였다.
