Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, Anna S. Park, Noah Schnitzer +28
Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…
The Breakdown of Mott Physics at VO Surfaces
Matthew J. Wahila, Nicholas F. Quackenbush, Jerzy T. Sadowski +12
Transition metal oxides such as vanadium dioxide (VO), niobium dioxide (NbO), and titanium sesquioxide (TiO) are known to undergo a temperature-dependent metal-insu…
Scalable Memdiodes Exhibiting Rectification and Hysteresis for Neuromorphic Computing
Joshua C. Shank, M. Brooks Tellekamp, Matthew J. Wahila +5
Metal-NbO-metal memdiodes exhibiting rectification, hysteresis, and capacitance are demonstrated for applications in neuromorphic circuitry. These devices do not requ…
Cooperative Effects of Strain and Electron Correlation in Epitaxial VO2 and NbO2
Wei-Cheng Lee, Matthew J. Wahila, Shantanu Mukherjee +9
We investigate the electronic structure of the epitaxial VO films in the rutile phase using the density functional theory combined with the slave spin method (DFT+SS). In DFT-S…
Diffuson-driven Ultralow Thermal Conductivity in Amorphous Nb2O5 Thin Films
Zhe Cheng, Alex Weidenbach, Tianli Feng +9
Niobium pentoxide (Nb2O5) has been extensively reported for applications of electrochemical energy storage, memristors, solar cells, light emitting diodes (LEDs), and electrochromi…
