Long-Lived Charge Separation Following Pump-Energy Dependent Ultrafast Charge Transfer in Graphene/WS Heterostructures
Shuai Fu, Indy du Fossé, Xiaoyu Jia +11
Van der Waals heterostructures consisting of graphene and transition metal dichalcogenides (TMDCs) have recently shown great promise for high-performance optoelectronic application…
Quantitative electrochemical control over optical gain in quantum-dot solids
Jaco J. Geuchies, Baldur Brynjarsson, Gianluca Grimaldi +4
Realizing solution processed quantum dot (QD) lasers is one of the holy-grails of nanoscience. The reason that QD lasers are not yet commercialized is that the lasing threshold is…

Positron Two Dimensional Angular Correlation of Annihilation Radiation (2D-ACAR) measurements reveal modifications of the electronic structure and composition at the surfaces of Pb…
Efficient photogeneration of charge carriers in silicon nanowires with a radial doping gradient
D. H. K. Murthy, T. Xu, W. H. Chen +11
From electrodeless time-resolved microwave conductivity measurements, the efficiency of charge carrier generation, their mobility, and decay kinetics on photo-excitation were studi…
Electronic coupling of colloidal CdSe nanocrystals monitored by thin-film positron-electron momentum density methods
S. W. H. Eijt, P. E. Mijnarends, L. C. van Schaarenburg +4
The effect of temperature controlled annealing on the confined valence electron states in CdSe nanocrystal arrays, deposited as thin films, was studied using two-dimensional angula…
Positron studies of surfaces, structure and electronic properties of nanocrystals
S. W. H. Eijt, B. Barbiellini, A. J. Houtepen +3
