Abstract

Abstract : Self‐Driven Near‐Infrared Photodetectors In article number 2206262, Hao Jin, Longbiao Huang, Zhenhua Sun, and co‐workers report that bulk photovoltaic effect (BPVE) is found in the SnTe film by Si doping though breaking the inversion symmetry. As a result, additional current originated from the BPVE is generated beyond the p‐n junctions, leading to an improvement of photocurrent by 7.5 times.
