Optical probing of the carriers-mediated coupling of the spin of two Co atoms in a quantum dot
L. Besombes, J. Kobak, W. Pacuski
We report on the optical spectroscopy of the spin of two Co atoms in a quantum dot and interacting with a single exciton. The spectrum of quantum dots containing two Co atoms are e…
Coupling of the triplet states of a negatively charged exciton in a quantum dot with the spin of a magnetic atom
L. Besombes, S. Ando, S. Kuroda +1
Two electrons in a quantum dot (QD) can form triplet states. We analyze the exchange coupling of the triplet states of the negatively charged exciton in a QD (X, two electrons…
Spin dynamics of positively charged excitons in Cr-doped quantum dots probed by resonant photoluminescence
V. Tiwari, M. Morita T. Inoue, S. Ando S. Kuroda +2
We study the dynamics of the spin system that consist of a positively charged II-VI semiconductor quantum dot doped with a single Cr ion. The resonant photoluminescence (PL) of…
A hole-Cr nano-magnet in a semiconductor quantum dot
V. Tiwari, M. Arino, S. Gupta +7
We study a new diluted magnetic semiconductor system based on the spin of the ionized acceptor Cr. We show that the negatively charged Cr ion, an excited state of the Cr in…
Radio-frequency stress-induced modulation of CdTe/ZnTe quantum dots
V. Tiwari, K. Makita, M. Arino +6
We demonstrate radio-frequency tuning of the energy of individual CdTe/ZnTe quantum dots (QDs) by Surface Acoustic Waves (SAWs). Despite the very weak piezoelectric coefficient of…
Optical control of an individual Cr spin in a semiconductor quantum dot
L. Besombes, H. Boukari, V. Tiwari +3
We demonstrate that the spin of a Cr atom in a quantum dot (QD) can be controlled optically and we discuss the main properties of this single spin system. The photoluminescence of…
