Anharmonic Fluctuations Govern the Band Gap of Halide Perovskites
Stefan A. Seidl, Xiangzhou Zhu, Guy Reuveni +5
We determine the impact of anharmonic thermal vibrations on the fundamental band gap of CsPbBr, a prototypical model system for the broader class of halide perovskite semicondu…
Optical detection of single electron spin resonance in a quantum dot
Martin Kroner, Kathrina M. Weiss, Benjamin Biedermann +8
We demonstrate optically detected spin resonance of a single electron confined to a self-assembled quantum dot. The dot is rendered dark by resonant optical pumping of the spin wit…
Contrast in transmission spectroscopy of a single quantum dot
B. D. Gerardot, S. Seidl, P. A. Dalgarno +5
We perform transmission spectroscopy on single quantum dots and examine the effects of a resident carriers spin, the incident laser spot size, polarization, and power on the experi…
Manipulating exciton fine-structure in quantum dots with a lateral electric field
B. D. Gerardot, S. Seidl, P. A. Dalgarno +8
The fine structure of the neutral exciton in a single self assembled InGaAs quantum dot is investigated under the effect of a lateral electric field. Stark shifts up to 1.5 meV, an…
Absorption and photoluminescence spectroscopy on a single self-assembled charge-tunable quantum dot
S. Seidl, M. Kroner, P. A. Dalgarno +8
We have performed detailed photoluminescence (PL) and absorption spectroscopy on the same single self-assembled quantum dot in a charge-tunable device. The transition from neutral…
Absorptive and dispersive optical responses of excitons in a single quantum dot
B. Alén, A. Högele, M. Kroner +6
We have determined both the real and imaginary parts of the dielectric polarizability of a single quantum dot. The experiment is based on the observation and the manipulation of Ra…
