Vapor-liquid-solid growth of highly-mismatched semiconductor nanowires with high-fidelity van der Waals layer stacking
Edy Cardona, Matthew K. Horton, Daniel Paulo-Wach +6
Nanobelts, nanoribbons and other quasi-one-dimensional nanostructures formed from layered, so-called, van der Waals semiconductors have garnered much attention due to their high-pe…
Charge Carrier Transport in Iron Pyrite Thin Films: Disorder Induced Variable Range Hopping
Sudhanshu Shukla, Sinu Mathew, Hwan Sung Choe +8
The origin of p-type conductivity and the mechanism responsible for low carrier mobility was investigated in pyrite (FeS2) thin films. Temperature dependent resistivity measurement…
Synthesis and electronic structure characterization of diamane
Feng Ke, Lingkong Zhang, Yabin Chen +13
Atomically thin graphite, known as graphene, has been a marvel in material science because of its exceptional properties, novel physics and promising applications. Atomically thin…
Black Arsenic: A Layered Semiconductor with Extreme in-plane Anisotropy
Yabin Chen, Chaoyu Chen, Robert Kealhofer +18
Two-dimensional (2D) layered materials emerge in recent years as a new platform to host novel electronic, optical or excitonic physics and develop unprecedented nanoelectronic and…
Anomalous Raman Spectra and Thickness Dependent Electronic properties of WSe2
H. Sahin, S. Tongay, S. Horzum +5
Typical Raman spectra of transition metal dichalcogenides (TMDs) display two prominent peaks, E2g and A1g, that are well separated from each other. We find that these modes are deg…
