A Modeling Study of Dislocation Sidewall Gettering in II-VI and III-V Semiconductor Heterostructures
Preview AbstractSince the invention of dislocation sidewall gettering (DSG) in 2000 the technique has been applied extensively in infrared focal-plane arrays and flat-panel displays. However, development of DSG technology has been guided mostly by empirical trials due to the lack of detailed physical models. Here we demonstrate the application of a dislocation dynamics model to evaluate DSG approaches in both ZnSySe1-y/GaAs (001) and InGaxAs1-x/GaAs (001) heterostructures. We find that the effectiveness of DSG is strongly dependent on composition in both material systems.
