Time-resolved energy transfer from single chloride terminated nanocrystals to graphene
, 2014 We examine the time-resolved resonance energy transfer of excitons from single n-butyl amine-bound, chloride-terminated nanocrystals to two-dimensional graphene through time-correlated single photon counting. The radiative biexponential lifetime kinetics

Ultrahigh Hot Carrier Transient Photocurrent in Nanocrystal Arrays by Auger Recombination. [PDF]
, 2019 In this report, we show that a new mechanism for carrier transport in solution-processed colloidal semiconductor nanocrystal arrays exists at high excitation intensity on ultrafast time scales and allows for facile intrinsic transport between as-prepared

A Deeper Insight into Strain for the Sila-bi[6]prismane (Si\u3csub\u3e18\u3c/sub\u3eH\u3csub\u3e12\u3c/sub\u3e) Cluster with its Endohedrally Trapped Silicon Atom, Si\u3csub\u3e19\u3c/sub\u3eH\u3csub\u3e12\u3c/sub\u3e [PDF]
, 2015 A new family of over-coordinated hydrogenated silicon nanoclusters with outstanding optical and mechanical properties has recently been proposed. For one member of this family, namely the highly symmetric Si19H12 nanocrystal, strain calculations have ...

Surface magnetization in non-doped ZnO nanostructures
, 2009 We have investigated the magnetic properties of non-doped ZnO nanostructures by using {\it ab initio} total energy calculations. Contrary to many proposals that ferromagnetism in non-doped semiconductors should be induced by intrinsic point defects, we ...
