Exciton fine structure and biexciton binding energy in single self-assembled InAs/AIAs quantum dots

Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2006)

The exciton and biexciton emissions of a series of single quantum dots of InAs in an AlAs matrix have been studied. These emissions consist of linear cross polarized doublets showing large values of both the biexciton ...
Resonant optical excitation of longitudinal-optical phonons and intermixing in InAsAlAs single quantum dots

Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Meyer, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2008)

Excitations of a single InAsAlAs self-assembled quantum dot were investigated by photoluminescence excitation spectroscopy. Resonant absorption by longitudinal-optical (LO) phonons of the quantum dot and the barriers is ...
Tuning the onset voltage of resonant tunneling through InAs quantum dots by growth parameters

Hapke-Wurst, I.; Zeitler, U.; Keyser, U.F.; Haug, Rolf J.; Pierz, Klaus; Ma, Z. (College Park, MD : American Institute of Physics, 2003)

A study was conducted on the onset voltage of resonant tunneling through indium arsenide (InAs) quantum dots by growth parameters. It was found that the onset voltage of the first step decreased from 200 mV to 0 with ...
