Observation of ~100% valley-coherent excitons in monolayer MoS2 through giant enhancement of valley coherence time
Garima Gupta, Kenji Watanabe, Takashi Taniguchi +1
In monolayer transition metal dichalcogenide semiconductors, valley coherence degrades rapidly due to a combination of fast scattering and inter-valley exchange interaction. This l…
Two-dimensional ReS2: Solution to the Unresolved Queries on Its Structure and Inter-layer Coupling Leading to Potential Optical Applications
Janardhan Rao Gadde+, Anasuya Karmakar+, Tuhin Kumar Maji+ +12
Over the last few years, ReS2 has generated a myriad of unattended queries regarding its structure, the concomitant thickness dependent electronic properties and apparently contras…
Accurate Extraction of Schottky Barrier Height and Universality of Fermi Level De-pinning of van der Waals Contacts
Krishna Murali, Medha Dandu, Kenji Watanabe +2
Due to Fermi level pinning (FLP), metal-semiconductor contact interfaces result in a Schottky barrier height (SBH), which is usually difficult to tune. This makes it challenging to…
Contact-Barrier Free, High Mobility, Dual-Gated Junctionless Transistor Using Tellurium Nanowire
Pushkar Dasika, Debadarshini Samantaray, Krishna Murali +5
Gate-all-around nanowire transistor, due to its extremely tight electrostatic control and vertical integration capability, is a highly promising candidate for sub-5 nm technology n…
Combinatorial Large-area MoS2/Anatase-TiO2 interface: A Pathway to Emergent Optical and Opto-electronic Functionalities
Tuhin Kumar Maji, J R Aswin, Subhrajit Mukherjee +15
Interface of transition metal dichalcogenide (TMDC) and high-k dielectric transition metal oxides (TMO) had triggerred umpteen discourses due to the indubitable impact of TMO in re…
