Supermoiré-trapped quadrupolar exciton
Anish Kumar, Suman Chatterjee, Kenji Watanabe +2
Moiré-trapped dipolar interlayer exciton in heterobilayers offers a rich platform to explore interaction-driven phenomena. Extending the number of layers to three and beyond leads…
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…
Low-dimensional platforms for single photon detection
Pushkar Dasika, Liza Jain, Varun Srivatsav Kondapally +3
A Single-Photon Detector (SPD) can detect extremely low intensity of electromagnetic wave - down to a single photon. Driven by the rapid developments in quantum information science…
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…
Room Temperature Single Photon Detection at 1550 nm using van der Waals Heterojunction
Nithin Abraham, Kenji Watanabe, Takashi Taniguchi +1
Single-photon detectors (SPDs) are crucial in applications ranging from space, biological imaging to quantum communication and information processing. The SPDs that operate at room…
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…
