Emission Dynamics of Rydberg Excitons in : Distinguishing Second Harmonic Generation from Secondary Emission
Kerwan Morin, Poulab Chakrabarti, Delphine Lagarde +5
Rydberg excitons in simultaneously give rise to two very different optical responses under resonant two-photon excitation: a coherent second-harmonic signal mediat…
Direct measurement of the lifetime and coherence time of Cu2O Rydberg excitons
Poulab Chakrabarti, Kerwan Morin, Delphine Lagarde +2
Rydberg states of excitons are promising quantum objects to engineer giant nonlinearities in a solid-state system. For this purpose, a deeper understanding of the dynamics of Rydbe…
Influence of Defects on the Valley Polarization Properties of Monolayer MoS Grown by Chemical Vapor Deposition
Faiha Mujeeb, Poulab Chakrabarti, Vikram Mahamiya +2
Here, the underlying mechanisms behind valley de-polarization is investigated in chemical vapor deposited 1L-MoS. Temperature dependent polarization resolved photoluminescenc…
Effect of strain and sulfur vacancies on the luminescence and valley polarization properties of CVD grown monolayer MoS films
Poulab Chakrabarti, Faiha Mujeeb, Subhabrata Dhar
Using temperature dependent photoluminescence (PL), polarization resolved PL and Raman spectroscopy, we investigate the effect of in situ vacuum annealing as well as the relaxation…
Effect of manganese incorporation on the excitonic recombination dynamics in monolayer MoS
Poulab Chakrabarti, Santosh Kumar Yadav, Swarup Deb +1
Using X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and Raman spectroscopy techniques we investigate the incorporation of Manganese (Mn) in monolayer (1L)-M…
Tunability of electrical and thermoelectrical properties of monolayer MoS through oxygen passivation
Swarup Deb, Pritam Bhattacharyya, Poulab Chakrabarti +4
Electric and thermoelectric properties of strictly monolayer MoS films, which are grown using a novel micro-cavity based CVD growth technique, have been studied under diverse e…
