Optical Determination of the Band Gap and Band Tail of Epitaxial AgZnSnSe at Low Temperature
S. Perret, Y. Curé, L. Grenet +3
We report on the precise determination of both the band gap E, and the characteristic energy of the band tail of localized defect states, for monocrystalline AgZ…
Generation of ultrashort (~10ps) spontaneous emission pulses by quantum dots in a switched optical microcavity
Emanuel Peinke, Tobias Sattler, Guilherme Monteiro Torelly +4
We report on the generation of few-ps long spontaneous emission pulses by quantum dots (QDs) in a switched optical microcavity. We use a pulsed optical injection of free charge car…
Effect of doping on the intersubband absorption in Si- and Ge-doped GaN/AlN heterostructures
A. Ajay, C. B. Lim, D. A. Browne +5
In this paper, we study band-to-band and intersubband characteristics of GaN/AlN heterostructures (planar and nanowires) structurally designed to absorb in the short-wavelength inf…
Large and uniform optical emission shifts in quantum dots externally strained along their growth axis
Petr Stepanov, Marta Elzo Aizarna, Joël Bleuse +6
We introduce a method which enables to directly compare the impact of elastic strain on the optical properties of distinct quantum dots (QDs). Specifically, the QDs are integrated…
Determination of the optimal shell thickness for self-catalysed GaAs/AlGaAs core-shell nanowires
R. Songmuang, Le Thuy Thanh Giang, J. Bleuse M. Den Hertog +2
We present a set of experimental results identifying various effects that govern the carrier dynamics of self-catalyzed GaAs/AlGaAs core-shell nanowires (NWs) grown by molecular be…
Long-lived excitons in GaN/AlN nanowire heterostructures
M. Beeler, C. B. Lim, P. Hille +6
GaN/AlN nanowire heterostructures can display photoluminescence (PL) decay times on the order of microseconds that persist up to room temperature. Doping the GaN nanodisk insertion…
