Confined exciton polaron in MoS on twisted-hBN
Garima Gupta, Mayank Chhaperwal, Pankaj Kumar +5
The simple electrostatic picture of a trion is that of an excess charge inducing an exciton polarization and binding closer (farther) to the hole (electron) side of it. Trion forma…
The origin and promise of transition metal dichalcogenide hosted single photon emitters for quantum technologies
Mayank Chhaperwal, Amartyaraj Kumar, Kausik Majumdar
Single photon emitters (SPEs) are integral parts of several quantum technology implementations. Over the past decade or so, monolayers of transition metal dichalcogenides (TMDCs) h…
Observation of moiré trapped biexciton through sub-diffraction-limit probing using hetero-bilayer on nanopillar
Mayank Chhaperwal, Suman Chatterjee, Suchithra Puliyassery +6
The ability to tune the degree of interaction among particles at the nanoscale is highly intriguing. The spectroscopic signature of such interaction is often subtle and requires sp…
Simultaneously enhancing brightness and purity of WSe single photon emitter using high-aspect-ratio nanopillar array on metal
Mayank Chhaperwal, Himanshu Madhukar Tongale, Patrick Hays +4
Monolayer semiconductor transferred on nanopillar arrays provides site-controlled, on-chip single photon emission, which is a scalable light source platform for quantum technologie…
