Abstract

In a lattice-matched <100> InP/Ga0.47In0.53As/Al0.48In0.52As system used for modulation-doped field effect transistors (MODFETs), low resistance ohmic contacts to the two-dimensional electron gas have been fabricated using alloyed NiGeAuAgAu metallization. In this work we examine the use of Auger electron spectroscopy (AES) and wavelength dispersive x-ray spectroscopy (WDX) analyses for studying the metal-semiconductor interactions and their correlation with measured ohmic contact resistance.
