Individual Vanadium Dopants Form Deep In-Gap States in Monolayer WS2
Tianhui Zhu, Carlos A. Gonzalez, Shihao Tu +11
Point defects in atomically thin materials have a strong impact on physical properties and those that induce in-gap states are advantageous for quantum information science and engi…
Resistive Switching Conducting Filament Electroformation with an Electrothermal Phase Field Method
John F. Sevic, Nobuhiko P. Kobayashi
A phase field method self-consistently coupled to continuum heat transport and charge conservation is used to simulate conducting filament dynamical evolution and nanostructure of…
Semiconductor-like Optical Properties Unveiled by Modeling of Short-Period Aluminum Oxide-Copper Multi-Layered Nanocomposites Deposited by Sputtering Atomic Layer Augmented Deposition (SALAD)
Søren A. Tornøe, Jacob H. Sands, Nobuhiko P. Kobayashi
In our previous publication, we discussed the optical properties of multi-layered nanocomposite samples consisting of 300 pairs of an AlOx layer and a Cu layer produced from sputte…
Laser-induced crystallization of copper oxide thin films: A comparison made between Gaussian and chevron-beam profiles provides a clue for the failure of Gaussian-beam profile
Willam Bodeau, Kaisei Otoge, Wenchang Yeh +1
The use of laser with a Gaussian-beam profile is frequently adopted in attempts of crystallizing non-single-crystal thin films; however, it merely results in the formation of poly-…
Impact of the nucleation of charge clusters on the retention of memristors: a self-consistent phase field computational study
Foroozan S. Koushan, Nobuhiko P. Kobayashi
In recent years, resistive RAM often referred to as memristor is actively pursued as a replacement for nonvolatile-flash memory due to its superior characteristics such as high den…
Visualization and Manipulation of Bilayer Graphene Quantum Dots with Broken Rotational Symmetry and Nontrivial Topology
Zhehao Ge, Frederic Joucken, Eberth Quezada +8
Electrostatically defined quantum dots (QDs) in Bernal stacked bilayer graphene (BLG) are a promising quantum information platform because of their long spin decoherence times, hig…
An electro-thermal computational study of conducting channels in dielectric thin films using self-consistent phase-field methodology: A view toward the physical origins of resistive switching
