Spectrally Selective Detection with In2O3-Si Radial Heterojunction Nanowire Photodiodes

摘要

We demonstrated radial heterojunction nanowire photodiodes consisting of an In₂O₃-shell/Si-core structure using conformal coating of an In₂O₃ layer on n-Si nanowires. We achieve selective spectral response from 400 to 700 nm by tuning the nanowire diameter. © 2019 The Author(s).
