Degenerately Doped Transition Metal Dichalcogenides as Ohmic Homojunction Contacts to Transition Metal Dichalcogenide Semiconductors [PDF]

ACS Nano, 2019
In search of an improved strategy to form low resistance contacts to MoS2 and related semiconducting transition metal dichalcogenides, we use ab initio density functional electronic structure calculations in order to determine the equilibrium geometry ...

Slippery Paraelectric Transition-Metal Dichalcogenide Bilayers

Nano Letters, 2022
Traditional ferroelectrics undergo thermally-induced phase transitions whereby their structural symmetry increases. The associated higher-symmetry structure is dubbed {\em paraelectric}. Ferroelectric transition metal dichalcogenide bilayers have been recently shown to become paraelectric, but not much has been said of the atomistic configuration of ...

Magnetism and metallicity in moiré transition metal dichalcogenides. [PDF]

Proc Natl Acad Sci U S A
The ability to control the properties of twisted bilayer transition metal dichalcogenides in situ makes them an ideal platform for investigating the interplay of strong correlations and geometric frustration. Of particular interest are the low energy scales, which make it possible to experimentally access both temperature and magnetic fields that are ...

Janus Monolayer Transition-Metal Dichalcogenides [PDF]

ACS Nano, 2017
A novel crystal configuration of sandwiched S-Mo-Se structure (Janus SMoSe) at the monolayer limit has been synthesized and carefully characterized in this work. By controlled sulfurization of monolayer MoSe2 the top layer of selenium atoms are substituted by sulfur atoms while the bottom selenium layer remains intact.

Transition-metal nitride halide dielectrics for transition-metal dichalcogenide transistors [PDF]

Nanoscale, 2022
Using first-principles calculations, we investigate six transition-metal nitride halides as potential vdW dielectrics for transition metal dichalcogenide channel transistors. We identify the best combinations for the p-MOS transistor technology.

Tunability of the Optical Properties of Transition-Metal-Based Structural Phase Change Materials

Optics, 2023
Phase transitions are an intriguing yet poorly understood aspect of transition-metal-based materials; these phase transitions can result in changes to the refractive index, absorption coefficient, and other optical properties of the materials. Transition-

Metal-insulator transition in transition metal dichalcogenide heterobilayer moiré superlattices [PDF]

Physical Review B, 2021
Moir superlattices formed in two-dimensional semiconductor heterobilayers provide a new realization of Hubbard model physics in which the number of electrons per effective atom can be tuned at will. We report on an exact diagonalization study of the electronic properties of half-filled narrow moir bands in which correlation strengths are varied by ...
