概要
- 論文の詳細を見る
Deep levels in semi-insulating GaAs were observed at low temperatures by means of improved thermally stimulated current (TSC) spectroscopy. The improvement was done by thinning the specimen and adding a guard ring electrode. The ionization energy of the levels was limited to below 0.7 eV. The concentration of 10^<13> cm^<-3> was easily measured with an electrode area of 5 mm^2. Spectra by electron traps and hole traps were separated by changing the bias polarity.
