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…
Charge fluctuations of a Cr atom probed in the optical spectra of a quantum dot
L. Besombes, H. Boukari, V. Tiwari +4
We study the emission of individual quantum dots in CdTe/ZnTe samples doped with a low concentration of Cr. In addition to dots with a photoluminescence (PL) split by the exchange…
Resonant photoluminescence and dynamics of a hybrid Mn-hole spin in a positively charged magnetic quantum dot
A. Lafuente-Sampietro, H. Boukari, L. Besombes
We analyze, through resonant photoluminescence, the spin dynamics of an individual magnetic atom (Mn) coupled to a hole in a semiconductor quantum dot. The hybrid Mn-hole spin and…
Resonant optical control of the spin of a single Cr atom in a quantum dot
A. Lafuente-Sampietro, H. Utsumi, H. Boukari +2
A Cr atom in a semiconductor host carries a localized spin with an intrinsic large spin to strain coupling particularly promising for the development of hybrid spin-mechanical syst…
Spin dynamics of an individual Cr atom in a semiconductor quantum dot under optical excitation
A. Lafuente-Sampietro, H. Utsumi, H. Boukari +2
We studied the spin dynamics of a Cr atom incorporated in a II-VI semiconductor quantum dot using photon correlation techniques. We used recently developed singly Cr-doped CdTe/ZnT…
Individual Cr atom in a semiconductor quantum dot: optical addressability and spin-strain coupling
A. Lafuente-Sampietro, H. Utsumi, H. Boukari +2
We demonstrate the optical addressability of the spin of an individual Chromium atom (Cr) embedded in a semiconductor quantum dot. The emission of Cr-doped quantum dots and their e…
Strain induced coherent dynamics of coupled carriers and Mn spins in a quantum dot
A. Lafuente-Sampietro, H. Boukari, L. Besombes
We report on the coherent dynamics of the spin of an individual magnetic atom coupled to carriers in a semiconductor quantum dot which has been investigated by resonant photolumine…
