| Abstract Scope |
Many 2D transition metal dichalcogenides (TMD) are promising for optical and electronic devices, but achieving consistent electrical contacts is challenging. We'll discuss a process for forming as-grown contacts to thin film TMDs, investigating growth mechanisms and contact properties. TMDs like MoS2 were chemically vapor deposited on substrates with transition metal contacts, serving as source material and self-forming contacts. Optical characterization reveals high-quality material. Electrical characterization often shows metal-semiconductor-metal (MSM) Schottky contacts with significant variation. Cross-sectional SEM imaging and post-growth contacts reveal a complex formation process, suggesting a potentially controllable thin metal-oxide layer. This understanding provides a path to tune the growth process to form consistent high-quality contacts in a scalable manner |
