Polaron-Driven Spin Funneling through Rashba-Split Bands in Mixed-Phase Quasi-Two-Dimensional Ruddlesden-Popper Perovskites
Sushovan Sarkar, Koushik Gayen, Ashish Soni +1
Metal halide perovskites (MHPs) exhibit pronounced spin-orbit coupling (SOC) as a result of their heavy metal constituents, leading to distinctive electronic properties such as Ras…
Bidirectional Photoinduced Carrier Transfer in Fluorinated Quasi-2D Perovskites Governing Enhanced Photocurrent Generation
Soumya Halder, Koushik Gayen, Nagendra S. Kamath +1
Quasi-two-dimensional (quasi-2D) metal halide perovskites exhibit rich phase heterogeneity that profoundly influences light-matter interactions and charge transport. However, the f…
Efficient Multiple Exciton Generation in Monolayer MoS2
Ashish Soni, Dushyant Kushavah, Li-Syuan Lu +2
Utilizing the excess energy of photoexcitation that is otherwise lost as thermal effects can improve the efficiency of next-generation light-harvesting devices. Multiple exciton ge…
Improvement of both performance and stability of photovoltaic devices by in situ formation of a sulfur-based 2D perovskite
Milon Kundar, Sahil Bhandari, Sein Chung +4
Perovskite solar cells (PSCs) with superior performance have been recognized as a potential candidate in photovoltaic technologies. However, the defects in active perovskite layer…
Valley Degree of Freedom in Two-Dimensional van der Waals Materials
Ashish Soni, Suman Kalyan Pal
Layered materials can possess valleys that are indistinguishable from one another except for the momentum. These valleys are individually addressable in momentum space at the K and…
In-plane anisotropic quantum confinement effect in ultrasmall SnS sheets
Abdus Salam Sarkar, Anita Kumari, Anchala +4
Black phosphorus (BP) analogous tin(II) sulfide (SnS) has recently emerged as an attractive building block for electronic devices due to its highly anisotropic response. Two-dimens…
High-Performance Perovskite Photodetectors Based on CH3NH3PbBr3 Quantum Dot/TiO2 Heterojunction
Rajeev Ray, Nagaraju Nakka, Suman Kalyan Pal
Organo-lead halide perovskite materials have opened up a great opportunity to develop high performance photodetectors because of their superior optoelectronic properties. The main…
Strong many-body interactions in ultrathin anisotropic tin (II) monosulfide
Abdus Salam Sarkar, Aamir Mushtaq, Dushyant Kushavah +1
Two-dimensional (2D) tin(II) monosulfide (SnS) with strong structural anisotropy has been proven to be a phosphorene analogue. However, difficulty in isolating very thin layer of S…
