Gelvez Rueda, M.C. (author), Peeters, Sicco (author), Wang, Peng Cheng (author), Felter, K.M. (author), Grozema, F.C. (author)In this work, we show that the quality of the precursor and the thin film preparation strongly affect the optoelectronic properties of the 2D perovskite BA<sub>2</sub>PbI<sub>4</sub>. 2D perovskites with alkylammonium organic cations such as butylammonium (BA) are relatively soft structures that exhibit large dynamic disorder and phase...journal article 2020

Wang, J. (author), Plissard, S. (author), Hocevar, M. (author), Vu, T.T.T. (author), Zehender, T. (author), Immink, G.G.W. (author), Verheijen, M.A. (author), Haverkort, J. (author), Bakkers, E.P.A.M. (author)We investigate the growth of vertically standing [100] zincblende InP nanowire (NW) arrays on InP (100) substrates in the vapor-liquid-solid growth mode using low-pressure metal-organic vapor-phase epitaxy. Precise positioning of these NWs is demonstrated by electron beam lithography. The vertical NW yield can be controlled by different...journal article 2012

Akopian, N. (author), Perinetti, U. (author), Wang, L. (author), Rastelli, A. (author), Schmidt, O.G. (author), Zwiller, V. (author)We study single GaAs quantum dots with optical transitions that can be brought into resonance with the widely used D2 transitions of rubidium atoms. We achieve resonance by Zeeman or Stark shifting the quantum dot levels. We discuss an energy stabilization scheme based on the absorption of quantum dot photoluminescence in a rubidium vapor. This...journal article 2010
