Scalable substitutional doping of two-dimensional (2D) transition metal dichalcogenides (TMDCs) is a prerequisite to developing next-generation logic and memory devices based on 2D materials. To date, doping efforts are still nascent. Here, we report scalable growth and vanadium (V) doping of 2D WSe2 at front-end-of-line (FEOL) and back-end-of-line (BEOL) compatible temperatures of 800 °C and 400 °C, respectively. A combination of experimental and theoretical studies confirm that vanadium atoms… Expand

Scalable Substitutional Re-Doping and its Impact on the Optical and Electronic Properties of Tungsten Diselenide.
A systematic study of scalable in situ doping of fully coalesced 2D WSe2 films with Re atoms via metal-organic chemical vapor deposition demonstrates a viable approach to introducing true dopant-level impurities with high precision, which can be scaled up to batch production for applications beyond digital electronics.

How Substitutional Point Defects in Two-Dimensional WS2 Induce Charge Localization, Spin-Orbit Splitting, and Strain.
The important role of charge localization, spin-orbit coupling, and strain for the formation of deep defect states observed at substitutional defects in WS2 as reported here will guide future efforts of targeted defect engineering and doping of TMDs. Expand
Tuning Electrical Conductance of MoS2 Monolayers through Substitutional Doping.
The study indicates that the dopant carriers do not fully ionize in the 2D limit, unlike in their 3D analogues, which is explained by weaker charge screening and impurity band conduction and the electrical conductivity is reproducibly tuned over seven orders of magnitude. Expand
Electrical suppression of all nonradiative recombination pathways in monolayer semiconductors
It is shown that the photoluminescence quantum yield of as-processed MoS2 and WS2 monolayers reaches near-unity when they are made intrinsic through electrostatic doping, without any chemical passivation. Expand
Growth of large-area and highly crystalline MoS2 thin layers on insulating substrates.
It is reported that the high-temperature annealing of a thermally decomposed ammonium thiomolybdate layer in the presence of sulfur can produce large-area MoS(2) thin layers with superior electrical performance on insulating substrates. Expand
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
The authors determine the atomic structure and electronic properties of chalcogen-site point defects common to monolayer MoSe2 and WS2, and find that these are substitutional defects, where a chalCogen atom is substituted by an oxygen atom, rather than vacancies. Expand
Tightly bound trions in monolayer MoS2.
The spectroscopic identification in a monolayer MoS(2) field-effect transistor of tightly bound negative trions, a quasiparticle composed of two electrons and a hole is reported, which has no analogue in conventional semiconductors. Expand
