Sub-mA/cm² dark current density, buffer-less Germanium (Ge) photodiodes on a 200-mm Ge-on-insulator substrate

Sub-mA/cm² dark current density, buffer-less Germanium (Ge) photodiodes on a 200-mm Ge-on-insulator substrate

In recent years, Germanium (Ge) photodiodes have established a widespread utilization in photonic-integrated circuits (PICs). However, the devices commonly exhibit a prominent dark current due to the substantial defects at the Ge/Si heteroepitaxial interface. Herein, we demonstrate normal-incidence,...
