Journal ArticleDOI
Oxygen vacancy and hole conduction in amorphous TiO2
Hieu H. Pham,Lin-Wang Wang +1 more
TL;DR: It is suggested that the oxygen vacancies and their defect states provide hopping channels, which are comparable to experimental observations and could be responsible for hole conduction in the "leaky" TiO2 recently discovered for the photochemical water-splitting applications.
Journal ArticleDOI
Quantum Mechanical Screening of Single-Atom Bimetallic Alloys for the Selective Reduction of CO2 to C1 Hydrocarbons
Mu Jeng Cheng,Mu Jeng Cheng,Ezra L. Clark,Ezra L. Clark,Hieu H. Pham,Alexis T. Bell,Alexis T. Bell,Martin Head-Gordon,Martin Head-Gordon +8 more
TL;DR: In this article, density functional theory (DFT) calculations combined with the Poisson-Boltzmann implicit solvation model are used to show that single-atom alloys (SAAs) are promising electrocatalysts for CO2 reduction to C1 hydrocarbons in aqueous solution.
Journal ArticleDOI
Surface Proton Hopping and Fast-Kinetics Pathway of Water Oxidation on Co3O4 (001) Surface
TL;DR: In this article, the authors proposed a mechanism of water splitting on cobalt oxide surface with atomistic thermodynamic and kinetic details, and showed that all nonelectrochemical reactions are kinetically fast and thermodynamically downhill.
Journal ArticleDOI
Finite-temperature elasticity of fcc Al: Atomistic simulations and ultrasonic measurements
Hieu H. Pham,Michael E. Williams,Patrick Mahaffey,Miladin Radovic,Raymundo Arroyave,Tahir Cagin +5 more
TL;DR: In this article, the authors investigated the temperature dependence of a simple metal, aluminum, and provided insight into various contributions to temperature dependence in elastic properties by investigating the thermoelastic properties of fcc aluminum.
Journal ArticleDOI
DFT+U studies of Cu doping and p-type compensation in crystalline and amorphous ZnS.
TL;DR: The formation of a complex that contains two CuZn and one S vacancy is highly favorable in both phases and the local environment of this charge-compensated Cu complex obtained by DFT calculations agrees well with the previous EXAFS measurements.
