摘要

本文提出了一个四层模型，其中包括深层和浅层受体和供体，允许预测HR GaAs:Cr材料和传感器的特性。结果表明，当EL2中心浓度为(1 ~ 3)∙1015 cm-3、Cr浓度约为1∙1017 cm-3、热受体浓度为(1 ~ 4)∙1016 cm-3时，HR GaAs:Cr材料的非平衡载流子寿命、霍尔迁移率和电阻率的模拟值与实验数据最吻合。结果表明，在LEC - HR GaAs:Cr中，EL2+和Cr离子化中心是决定非平衡电子和空穴寿命的主要深层能级。

Simulation of lateral distribution of resistivity and charge carrier lifetime in chromium-compensated gallium arsenide wafers

The paper proposes a four-level model which includes deep and shallow acceptors and donors, allowing to predict characteristics for the HR GaAs:Cr material and sensors. It is shown that the best agreement between the simulated values and experimental data of the non-equilibrium charge carrier lifetime, Hall mobility, and resistivity of the HR GaAs:Cr material, is achieved at the EL2 center concentration in the range of (1 to 3)∙10¹⁵ cm^–3, the Cr concentration of about 1∙10¹⁷ cm^–3, and the concentration of thermal acceptors in the range of (1 to 4)∙10¹⁶ cm^–3. It is shown that EL2⁺ and Cr ionized centers are the dominant deep levels that determine the lifetime of respectively non-equilibrium electrons and holes in LEC HR GaAs:Cr.
