Single-valley high-mobility (110) AlAs quantum wells with anisotropic mass
S. Dasgupta, S. Birner, C. Knaak +4
We studied a doping series of (110)-oriented AlAs quantum wells (QWs) and observed transport evidence of single anisotropic-mass valley occupancy for the electrons in a 150 Åwide Q…
A Charge and Spin Readout Scheme For Single Self-Assembled Quantum Dots
D. Heiss, V. Jovanov, M. Bichler +2
We propose an all optical spin initialization and readout concept for single self assembled quantum dots and demonstrate its feasibility. Our approach is based on a gateable single…
Cavity-resonant excitation for efficient single photon generation
M. Kaniber, A. Neumann, A. Laucht +3
We present an efficiently pumped single photon source based on single quantum dots (QD) embedded in photonic crystal nanocavities. Resonant excitation of a QD via a higher order ca…
Nanometer-scale sharpness in corner-overgrown heterostructures
L. Steinke, P. Cantwell, D. Zakharov +6
A corner-overgrown GaAs/AlGaAs heterostructure is investigated with transmission and scanning transmission electron microscopy, demonstrating self-limiting growth of an extremely s…
Investigation of Non Resonant Dot - Cavity Coupling in Two Dimensional Photonic Crystal Nanocavities
M. Kaniber, A. Laucht, A. Neumann +4
We study the optical emission from single semiconductor quantum dots coupled to the optical modes of photonic crystal nanocavities. For dots that are both spectrally and spatially…
Hopping conduction in strongly insulating states of a diffusive bent quantum Hall junction
L. Steinke, D. Schuh, M. Bichler +2
Transport studies of a bent quantum Hall junction at integer filling factors show strongly insulating states at higher fields. In this paper we analyze the strongly insulating beha…
