Abstract
A room-temperature spatially resolved and polarization resolved photol uminescence (PL) technique is demonstrated to be a useful tool for stu dying the intermixing process in InGaAsP multiple-quantum-well systems disordered by focused ion beam implantation. This technique produces maps of the spectral uniformity, degree of polarization, and PL yield at room temperature. Information on spectral shift (i.e., bandgap chan ge) and anisotropy in the implanted region can be obtained from these maps. A significant enhancement in pi yield (up to 40%) for Si+ implan ted line patterns was observed.
