Three Pulse DLTS Method Proposed to Eliminate the Edge Region Effect and its Applications to the Measurements of DX-Centers Capture Barriers of
消除边缘区效应的“三脉冲DLTS”法及对DX-中心俘获过程的测量

The authors developed a new method-Three Pulse DLTS method-for the measurementof the capture cross-section of deep levels. The effect of edge region can be eliminatedWe have also meaured the capture cross-section of the DX-center in Al_x Ca_(1-x)As:Si sampleswith different Al mole fraction x by the method and have got some satisfied results aidedby computer regression process in which,the high concentrations of deep center have beentaken into account.
