Study of GaInP/GaAs/GaInP Double Heterostructures Grown by MOCVD with Photoreflectance and Photoluminescence
Published online by Cambridge University Press: 22 February 2011
Abstract
The GaInP-GaAs single quantum well structures grown by metal-organic chemical vapor deposition (MOCVD) were investigated by photoreflectance (PR) and photoluminescence (PL) spectroscopies. The built-in electric field in the GaAs close to the top surface was evaluated using the observed Franz-Keldysh oscillations. The fundamental energy gaps and broadening parameters were also determined. The full width at half maximum (FWHM) of the GaInP PL peak is 11 meV
