TL;DR
This study investigates how pulsed light induces photocurrent in nitrogen-doped single-crystal diamond and how continuous illumination can quench and recover this photocurrent, informing diamond electronics and sensors.
Contribution
It demonstrates optical quenching and recovery of photocurrent in diamond, providing insights for diamond-based electronic and sensing applications.
Findings
Pulsed light induces photocurrent in nitrogen-doped diamond.
Continuous-wave light can quench the photocurrent.
Recovery of photocurrent is characterized and understood.
Abstract
We study the photocurrent induced by pulsed-light illumination (pulse duration is several nanoseconds) of single-crystal diamond containing nitrogen impurities. Application of additional continuous-wave light of the same wavelength quenches pulsed photocurrent. Characterization of the optically quenched photocurrent and its recovery is important for the development of diamond based electronics and sensing.
