Hot electrons in a nanowire hard X-ray detector

Autor: Maximilian Zapf, Maurizio Ritzer, Lisa Liborius, Andreas Johannes, Martin Hafermann, Sven Schönherr, Jaime Segura-Ruiz, Gema Martínez-Criado, Werner Prost, Carsten Ronning

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-7 (2020)

Designing efficient nanowire chip-based electrical and optical devices remains a challenge. Here, the authors present an axial p-n junction GaAs nanowire X-ray detector that enables achieving a spatial resolution of 200 nm; probing the internal elect
