چکیده
The 2H molybdenum telluride (MoTe2) photodetector structures were made with inserting 1T-MoTe2 interlayer contacts. optical response properties such as photoconductivity (PC) spectroscopy, illumination intensity dependent photoresponsivity, frequency photocurrent, and time-resolved photoresponse carried out in this study. In PC spectra, a much higher photoresponsivity of 2H-MoTe2 observed by contact. photocurrent investigations explore the carrier kinetic decay process MoTe2 different electrode Schottky barrier heights (SBH) extracted thermionic emission theory also investigated results show potential applicability for photodetection devices based layered transition metal dichalcogenides semiconductors.

KGaA, Weinheim wileyonlinelibrary.com (1 of 8) 1603491 In this family, thin layers of transition metal dichalcogenides (TMDs) with the formula MX2 (M = transition metal of group 4–10; X = S, Se, or Te) are particularly attractive for optoelectronics applications.[7,8] For example, several bulk TMDs are indirect bandgap semiconductors, but will become direct ba...
متن کاملMonolayer Single-Crystal 1T'-MoTe2 Grown by Chemical Vapor Deposition Exhibits Weak Antilocalization Effect.
Growth of transition metal dichalcogenide (TMD) monolayers is of interest due to their unique electrical and optical properties. Films in the 2H and 1T phases have been widely studied but monolayers of some 1T'-TMDs are predicted to be large-gap quantum spin Hall insulators, suitable for innovative transistor structures that can be switched via a topological phase transition rather than convent...
متن کاملSynthesis of High-Quality Large-Area Homogenous 1T' MoTe2 from Chemical Vapor Deposition.
High-quality large-area few-layer 1T' MoTe2 films with high homogeneity are synthesized by the controlled tellurization of MoO3 film. The Mo precursor plays a key role in determining the quality and morphology of the 1T' MoTe2 . Furthermore, the amount of Te strongly influences the phase of the MoTe2 . The growth method paves the way toward the scalable production of 1T' MoTe2 -based applications.
متن کاملEnhanced Sensitivity of MoTe2 Chemical Sensor through Light Illumination
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) semiconducting materials have recently attracted wide attention and been regarded as promising building blocks for chemical sensors due to their high surface-to-volume ratio. However, their low response hinders the realization of high-performance 2D TMDCs chemical sensors. Here, we demonstrate the improvement of sensing performance o...
متن کاملAmbipolar MoTe2 transistors and their applications in logic circuits.
We report ambipolar charge transport in α-molybdenum ditelluride (MoTe2 ) flakes, whereby the temperature dependence of the electrical characteristics was systematically analyzed. The ambipolarity of the charge transport originated from the formation of Schottky barriers at the metal/MoTe2 contacts. The Schottky barrier heights as well as the current on/off ratio could be modified by modulating...
