Voltage-Regulated Photoluminescence Modulation in a 0D-2D Mixed Dimensional Heterostructure
S. V. U. Vedhanth, Amit Bhunia, Mohit Kumar Singh +3
Bias dependent oscillations in excitonic photoluminescence are observed in a mixed dimensional 0D 2D heterostructure. These oscillations arise from modulation by oscillatory DC pho…
Site-specific stable deterministic single photon emitters with low Huang-Rhys value in layered hexagonal boron nitride at room temperature
Amit Bhunia, Pragya Joshi, Nitesh Singh +2
Development of stable room-temperature bright single-photon emitters using atomic defects in hexagonal-boron nitride flakes (h-BN) provides significant promises for quantum technol…
0D-2D Heterostructure for making very Large Quantum Registers using itinerant Bose-Einstein Condensate of Excitons
Amit Bhunia, Mohit Kumar Singh, Maryam Al Huwayz +2
Presence of coherent resonant tunneling in quantum dot (zero-dimensional) - quantum well (two-dimensional) heterostructure is necessary to explain the collective oscillations of av…
Phase Coherent Oscillations of Excitonic Photocapacitance and Bose-Einstein Condensation in Quantum Coupled 0D-2D Heterostructure
Amit Bhunia, Mohit Kumar Singh, Maryam Al Huwayz +2
We report quantum coherent oscillations of photocapacitance of a double-barrier resonant tunneling heterostructure with bias at 10 K. Periodic presence and absence of sharp exciton…
Experimental evidences of trions and Fermi edge singularity in single barrier GaAs/AlAs/GaAs heterostructure using photocapacitance spectroscopy
Amit Bhunia, Mohit Kumar Singh, Y. Galvao Gobato +2
In this paper, we show how photocapacitance spectra can probe two dimensional excitonic complexes and Fermi edge singularity as a function of applied bias around 100 K. In lower de…
Experimental evidences of quantum confined 2D indirect excitons in single barrier GaAs/AlAs/GaAs heterostructure using photocapacitance at room temperature
Amit Bhunia, Mohit Kumar Singh, Y. Galvao Gobato +2
We investigated excitonic absorptions in GaAs/AlAs/GaAs single barrier heterostructure using both photocapacitance and photocurrent spectroscopies at room temperature. Photocapacit…
Negative activation energy and dielectric signatures of excitons and excitonic Mott transitions in quantum confined laser structures
Amit Bhunia, Kanika Bansal, Mohamed Henini +2
Mostly, optical spectroscopies are used to investigate the physics of excitons, whereas their electrical evidences are hardly explored. Here, we examined a forward bias activated d…
