Experimental realization of scanning quantum microscopy
V. F. Gili, C. Piccinini, M. Safari Arabi +6
Quantum imaging is an ever expanding research field, in which the aim is to exploit the quantum nature of light to enhance image reconstruction capabilities. Despite a number of su…
Excited state spectroscopy and spin splitting in atomically thin quantum dots
P. Kumar, H. Kim, S. Tripathy +4
Semiconducting transition metal dichalcogenides (TMDCs) are very promising materials for quantum dots and spin-qubit implementation. Reliable operation of spin qubits requires the…
Spectral broadening of optical transitions at tunneling resonances in InAs/GaAs coupled quantum dot pairs
P. Kumar, C. Jennings, M. Scheibner +3
We report on linewidth analysis of optical transitions in InAs/GaAs coupled quantum dots as a function of bias voltage, temperature, and tunnel coupling strength. A significant lin…
Fluctuation-induced current from freestanding graphene: toward nanoscale energy harvesting
P. M. Thibado, P. Kumar, Surendra Singh +3
At room temperature, micron-sized sheets of freestanding graphene are in constant motion even in the presence of an applied bias voltage. We quantify the out-of-plane movement by c…
A strain-tunable quantum dot embedded in a nanowire antenna
P. E. Kremer, A. C. Dada, P. Kumar +4
We demonstrate an elastically-tunable self-assembled quantum dot in a nanowire antenna that emits single photons with resolution-limited spectral linewidths. The single-photon devi…
