Modulated Photoluminescence of Germanium via Intense Terahertz Pulse Electric Fields

Not Accessible

Your library or personal account may give you access

Abstract

We show a nonlinear effect of intense terahertz pulse electric fields (>200 kV/cm) on the photoluminescence of bulk germanium. Terahertz-pulse-induced direct-gap photoluminescence quenching is observed.
