Impact of excitation energy on hot carrier properties in InGaAs MQW structure
Hamidreza Esmaielpour, Laurent Lombez, Maxime Giteau +2
Hot carrier solar cells aim to overcome the theoretical limit of single-junction photovoltaic devices by suppressing the thermalization of hot carriers and extracting them through…
Strong Performance Enhancement in Lead-Halide Perovskite Solar Cells through Rapid, Atmospheric Deposition of n-type Buffer Layer Oxides
Ravi D. Raninga, Robert A. Jagt, Solène Béchu +12
Thin (approximately 10 nm) oxide buffer layers grown over lead-halide perovskite device stacks are critical for protecting the perovskite against mechanical and environmental damag…
Quasi-thermalization of collisionless particles in quadrupole potentials
Johnathan Lau, Olga Goulko, Thomas Reimann +4
We analyze several puzzling features of a recent experiment with a noninteracting gas of atoms in a quadrupole trap. After an initial momentum kick, the system reaches a stationary…
Quantitative Assessment of Carrier Density by Cathodoluminescence. II. GaAs nanowires
Hung-Ling Chen, Romaric De Lépinau, Andrea Scaccabarozzi +4
Precise control of doping in single nanowires (NWs) is essential for the development of NW-based devices. Here, we investigate a series of MBE-grown GaAs NWs with Be (p-type) and S…

Design and modification of the interfaces, always a critical issue for semiconductor devices, has become the primary tool to harness the full potential of halide perovskite (HaP)-b…
Combinatorial interpretations of Lucas analogues of binomial coefficients and Catalan numbers
Curtis Bennett, Juan Carrillo, John Machacek +1
The Lucas sequence is a sequence of polynomials in s, and t defined recursively by {0}=0, {1}=1, and {n}=s{n-1}+t{n-2} for n >= 2. On specialization of s and t one can recover the…
