Effects of Dislocations on Minority Carrier Lifetime in Dislocated Float Zone Silicon

Research output: Contribution to conference › Paper

Abstract

We present a correlation of Microwave Photoconductance Decay minority carrier lifetime with dislocation density in high purity Float Zone silicon. Electron Beam Induced Current (EBIC) images were carefully aligned to lifetime maps and depth profiling of individual defect electrical activity was done by varying the bias of Schottky diodes. The data presented provides a relationship betweenlifetime variations and EBIC contrast, based on dislocation density and impurity decoration in the near surface zone.
