Chemical Characterization of Arrays of TiO2 Nanocolumns

Lead Institution

University of Texas at Austin

Principal Investigator

David Flaherty

Project type

Exploratory Research

We propose to study thin nano-structured films of titanium oxide, and vanadium- and nitrogen-doped titanium oxide which we will deposit by employing reactive ballistic deposition (RBD). Properly…

Electrical and Photoelectrochemical Characterization of Single Crystal Bismuth Vanadate

Lead Institution

University of Texas at Austin

Principal Investigator

C. Buddie Mullins

Project type

Exploratory Research

Bismuth vanadate (BiVO4) is a promising electrode material in photoelectrochemical (PEC) cells. Recently, it has been shown that doping with Mo and W dramatically improves its performance, but the…

Small polaron hopping in epitaxial hematite films

Project type

Limited Scope

Iron oxide (hematite) has emerged as a promising material for photoelectrochemical (PEC) water splitting, where charge transport is often cited as a bottleneck to high efficiencies. It is also…
