Liquid phase exfoliation (LPE) of non-van der Waals materials has added a new feature to the research frontier two-dimensional materials. However, these LPE reports mostly focus on structures sheets. The information and insights into their local electronic properties are often missing. In this first such report, using atomic-scale characterization theoretical calculations, we discuss adsorption borophene Au(111) identify adsorbed be β12 phase. It is seen metallic as opposed insulating bulk...
Defects in semiconductors play a crucial role modifying their electronic structure and transport properties. In transition metal dichalcogenides, atomic chalcogen vacancies are primary source of intrinsic defects. While the impact these on electrical has been widely studied, exact remains not fully understood. this work, we correlate optical spectroscopy, low-temperature measurements, scanning tunneling microscopy (STM), first-principles density functional theory (DFT) calculations to...
Atomic vacancies, such as chalcogen vacancies in 2D TMDs, are important changing the host material's electronic structure and transport properties. We present a straightforward one-step method for growing monolayer MoS2 utilizing oxidized Molybdenum (Mo) foil using CVD delve into properties of as-grown samples. Devices fabricated from these sheets exhibit excellent electrical responses, with standout device achieving mobility exceeding 100 cm2V-1s-1. Structural analysis optical signatures...
We investigate the metallic van der Waals itinerant ferromagnet ${\mathrm{Fe}}_{5\ensuremath{-}x}{\mathrm{GeTe}}_{2}$ with atomic scale, spatially resolved low-temperature scanning tunneling microscopy (STM), and spectroscopy (STS). STM images unveil a new structural order $2a\phantom{\rule{0.16em}{0ex}}\ifmmode\times\else\texttimes\fi{}\phantom{\rule{0.16em}{0ex}}1a$ along known $\sqrt{3}a\phantom{\rule{0.16em}{0ex}}\ifmmode\times\else\texttimes\fi{}\phantom{\rule{0.16em}{0ex}}\sqrt{3}a$...
