Engineered Metal Alloys for Ultrafast-Broadband Short-Wave Infrared Photodetectors

Abstract

Investigate the structural and SWIR (1700 nm 2500 nm) optical properties of ultrathin transition metal alloy films deposited on silicon.The PI hypothesizes that AuxPd1-x and CuxTi1-x will form disordered alloys with broadband absorption in the SWIR range. This is based on prior experimental work and first-principles simulations. The PI will use grazing incidence x-ray diffraction to verify the structural properties and spectroscopic ellipsometry to collect the complex permittivity of the alloy thin films over a broad range of stoichiometries.
