Özet

An investigation of the Photoconductivity (PC) and In-plane Photovoltage (IPV) response of an undoped GaInNAs quantum well (QW) was carried out in the transient and steady-state modes using the 1.064 mu m line of a Nd: YAG laser as the excitation source. In this paper we focus on the behaviour of the nonlinear response of the transient PC (TPC) signal to excitation intensity. All PC measurements were performed at room temperature. Temperature and excitation intensity were considered instead in the study of the IPV signal.
