Room Temperature Formation of Carbon Onions via Ultrasonic Agitation of MoS2 in Isopropanol
Andrew J. Stollenwek, Eric Clausen, Matthew Cook +5
Ultrasonic agitation is a proven method for breaking down layered materials such as MoS2 into single or few layer nanoparticles. In this experiment, MoS2 powder is sonicated in iso…
Screening limited switching performance of multilayer 2D semiconductor FETs: the case for SnS
Sukrit Sucharitakul, Rajesh Kumar Ulaganathan, Raman Sankar +6
Gate tunable p-type multilayer tin mono-sulfide (SnS) field-effect transistor (FET) devices with SnS thickness between 50 and 100 nm were fabricated and studied to understand their…
Interlayer breathing and shear modes in NbSe2 atomic layers
Rui He, Jeremiah van Baren, Jia-An Yan +6
Atomically thin NbSe2 is a metallic layered transition metal dichalcogenide (TMD) with considerably different crystallographic structure and electronic properties from other TMDs,…
Distinct surface and bulk charge density waves in ultrathin 1T-TaS2
Rui He, Junichi Okamoto, Zhipeng Ye +10
We employ low-frequency Raman spectroscopy to study the nearly commensurate (NC) to commensurate (C) charge density wave (CDW) transition in 1T-TaS2 ultrathin flakes protected from…
