Quantum Emitter Localization in Layer-Engineered Hexagonal Boron Nitride.
ACS Nano, 2021 Hexagonal boron nitride (hBN) is a promising host material for room-temperature, tunable solid-state quantum emitters. A key technological challenge is deterministic and scalable spatial emitter localization, both laterally and vertically, while ...

Fluctuation and Noise Letters, 2016 A Brownian harmonic oscillator, which dissipates energy either by friction or via emission of electromagnetic radiation, is considered. This Brownian emitter is driven by the surrounding thermo-quantum fluctuations, which are theoretically described by the fluctuation–dissipation theorem.

Emittance theory for cylindrical fiber selective emitter [PDF]
AIP Conference Proceedings, 1999 A fibrous rare earth selective emitter is approximated as an infinitely long, cylinder. The spectral emittance, e(sub x), is obtained L- by solving the radiative transfer equations with appropriate boundary conditions and uniform temperature. For optical depth, K(sub R), where alpha(sub lambda), is the extinction coefficient and R is the cylinder ...

Photon Emission Rate Engineering using Graphene Nanodisc Cavities [PDF]
, 2014 In this work, we present a systematic study of the plasmon modes in a system of vertically stacked pair of graphene discs. Quasistatic approximation is used to model the eigenmodes of the system.
