Abstract: Two-dimensional transition metal dichalcogenides (TMDCs) have shown great promise in electronics and optoelectronics due to their unique electrical and optical properties. Heterostructured TMDC layers such as the laterally stitched TMDCs offer the advantages of better electronic contact and easier band offset tuning. Here, we demonstrate a photoresist-free focused ion beam (FIB) method to pattern as-grown TMDC monolayers by chemical vapor deposition, where the exposed edges from FIB etching serve as the seeds for growing a second TMDC material to form desired lateral heterostructures with arbitrary layouts. The proposed lithographic and growth processes offer better controllability for fabrication of the TMDC heterostrucuture, which enables the construction of devices based on heterostructural monolayers.

Growth of 2H stacked WSe₂ bilayers on sapphire

Publisher: Royal Society of Chemistry (RSC)

Date: 2019

DOI: 10.1039/C9NH00260J

Abstract: Bilayer WSe 2 nuclei were initially grown along the atomic steps of a sapphire substrate, resembling a “graphoepitaxial mechanism” and gradually formed into overlapped 2H stacked WSe 2 bilayers.

Intercorrelated In-Plane and Out-of-Plane Ferroelectricity in Ultrathin Two-Dimensional Layered Semiconductor In

Publisher: American Chemical Society (ACS)

Date: 05-02-2018

DOI: 10.1021/ACS.NANOLETT.7B04852

Abstract: Enriching the functionality of ferroelectric materials with visible-light sensitivity and multiaxial switching capability would open up new opportunities for their applications in advanced information storage with erse signal manipulation functions. We report experimental observations of robust intralayer ferroelectricity in two-dimensional (2D) van der Waals layered α-In
