Abstract
In this study, we report on a novel approach to produce â¼12 nm thick few-layer monoclinic 1T'-MoTe2 films. The deposition method comprised sputtering of Mo, molecular beam epitaxy of Te, and rapid thermal processing to effect tellurization of the Mo into 1T'-MoTe2. The heating rate and annealing time are the critical factors. 30 °C sâ1 heating rate and 2 min annealing at 470 °C were adopted in this work. X-ray photoelectron spectroscopy confirmed the formation of stoichiometric 1T'-MoTe2 films, while X-ray diffraction confirmed the monoclinic polymorph. Raman spectroscopy confirmed spatial uniformity over the sample size of 1 cm Ã 1.5 cm. Our fast synthesis approach to realize high-quality 1T'-MoTe2 paves the way towards the large-scale application of 1T'-MoTe2 in high-performance nanoelectronics and optoelectronics.
