Stimulated quantum phase slips from weak electromagnetic radiations in superconducting nanowires
Amir Jafari-Salim, Amin Eftekharian, A. Hamed Majedi +1
We study the rate of quantum phase slips in an ultranarrow superconducting nanowire exposed to weak electromagnetic radiations. The superconductor is in the dirty limit close to th…
Superconducting Nanowire Single Photon Detector on Diamond
Haig A. Atikian, Amin Eftekharian, A. Jafari Salim +4
Superconducting nanowire single photon detectors (SNSPDs) are fabricated directly on diamond substrates and their optical and electrical properties are characterized. Dark count pe…
Reduced Dark Counts in Optimized Geometries for Superconducting Nanowire Single photon Detectors
Mohsen K. Akhlaghi, Haig Atikian, Amin Eftekharian +2
We have experimentally compared the critical current, dark count rate and photo-response of 100nm wide superconducting nanowires with different bend designs. Enhanced critical curr…
Design of GaN White Light Emitting Diode through Envelope Function Analysis and Combined k.p-Transfer Matrix Method
Milad Khoshnegar, Majid Sodagar, Amin Eftekharian +1
In this paper, we present an envelope function analysis in order to design the emission spectra of a white quantum well light emitting diode. The nanometric heterostructure that we…
Exciton-photon interaction in a quantum dot embedded in a photonic microcavity
Majid Sodagar, Milad Khoshnegar, Amin Eftekharian +1
We present a detailed analysis of exciton-photon interaction in a microcavity made out of a photonic crystal slab. Here we have analyzed a disk-like quantum dot where an exciton is…
