Current-Voltage Characteristics of Hg_(1-x)Cd_xTe p-n Junctions under Hydrostatic Pressure
流体静压力下Hg_(1-x)Cd_xTe p-n结的伏安特性

The hydrostatic pressure dependence of the current-voltage characteristics of Hg_(1-x)Cd_xTep-n junctions with x=0.5 has been studied at room temperature and 77K.The pressure coefficientof the energy gap Eg was obtained.It is found that Eg increases linearly with pressure inthe low pressure range 01.4Pa) atroom temperature, Eg versus pressure deviates from this linearity remarkably. It is als observedthat, in the small forward and reverse bias region,the pressure dependence of the I-V characteristicsexhibits an "anomalous" bchavior.
