Nondestructive, Room Temperature Determination Of The Nature Of The Band-Bending (Carrier Type) In Group III Nitrides Using Contactless Electroreflectance And Surface Photovoltage Spectroscopy
Published online by Cambridge University Press: 10 February 2011
Abstract
Using contactless electroreflectance and surface photovoltage spectroscopy at room temperature we have nondestructively evaluated the band bending (carrier type) at the surface of epitaxial n- and p-type GaN/sapphire samples as well as at both the InGaN surface and the GaN at the InGaN/GaN interface of samples of epitaxial InGaN grown on top of thick GaN epilayers/sapphire, having average n- and p-type character.
