文摘

The mobilities of undoped (DSB) and doped (DSB⊂Tc, DSB⊂Pc) crystals have been measured. All the mobilities are in the same order of magnitude by FET and SCLC method. The structural-ordering retention is critical for the high mobility of doped crystal. The increase of crystal thickness is beneficial for improving the utilization of injected charges in the vertical-configuration diode.
