利用霍尔效应、电流-电压(I-V)、光致发光谱(PL)和光电流谱(PC)研究了不同掺铁浓度的半绝缘InP的性质.半绝缘InP的I-V特性明显地依赖于掺铁的浓度.掺铁的浓度也对半绝缘InP的光学性质和材料中缺陷的形成有影响.用PL和PC分别研究了掺铁半绝缘InP的禁带收缩现象和材料中的缺陷.

Properties of Fe-doped semi-insulating (SI) InP with different iron concentrations are studied by using Hall effect,current-voltage (I-V),photoluminescence spectroscopy (PL) and photocurrent spectroscopy(PC)measurements.I-V characteristics of SI InP strongly depend on Fe doping concentration.Fe doping concentration also influences optical properties and defective formation in as-grown SI InP.Band-gap narrowing phenomenon and defects in Fe doped SI InP are studied using PL and PC.
