Record high efficiency single-walled carbon nanotube/silicon p-n junction solar cells.
Carrier transport characteristics in high-efficiency single-walled carbon nanotubes (SWNTs)/silicon (Si) hybrid solar cells are presented. The solar cells were fabricated by depositing intrinsicExpand

Microfabrication technology: Organized assembly of carbon nanotubes
Nanoscale structures need to be arranged into well-defined configurations in order to build integrated systems. Here we use a chemical-vapour deposition method with gas-phase catalyst delivery toExpand

Synthesis and characterization of Ge2Sb2Te5 nanowires with memory switching effect.
Ge2Sb2Te5 nanowires (NWs) were synthesized by vaporizing GeTe, Sb, and Te precursors assisted by metal catalysts. Current-voltage measurement of the Ge2Sb2Te5 NW device displays fast and reversibleExpand

Core-shell heterostructured phase change nanowire multistate memory.
Phase-change memory, which switches reversibly between crystalline and amorphous phases, is promising for next generation data-storage devices. In this work, we present a novel, nonbinaryExpand

Synthesis of SnTe nanoplates with {100} and {111} surfaces.
SnTe is a topological crystalline insulator that possesses spin-polarized, Dirac-dispersive surface states protected by crystal symmetry. Multiple surface states exist on the {100}, {110}, and {111}Expand

Extremely low drift of resistance and threshold voltage in amorphous phase change nanowire devices
Time-dependent drift of resistance and threshold voltage in phase change memory (PCM) devices is of concern as it leads to data loss. Electrical drift in amorphous chalcogenides has been argued to beExpand

Recent Advances in Two-Dimensional Materials beyond Graphene.
The isolation of graphene in 2004 from graphite was a defining moment for the "birth" of a field: two-dimensional (2D) materials. In recent years, there has been a rapidly increasing number of papersExpand

Asymmetric Supercapacitor Electrodes and Devices.
The world is recently witnessing an explosive development of novel electronic and optoelectronic devices that demand more-reliable power sources that combine higher energy density and longer-termExpand

Metal seed layer thickness-induced transition from vertical to horizontal growth of MoS2 and WS2.
Two-dimensional (2D), layered transition metal dichalcogenides (TMDCs) can grow in two different growth directions, that is, horizontal and vertical. In the horizontal growth, 2D TMDC layers grow inExpand

Size-dependent surface-induced heterogeneous nucleation driven phase-change in Ge2Sb2Te5 nanowires.
By combining electron microscopy and size-dependent electrical measurements, we demonstrate surface-induced heterogeneous nucleation-dominant mechanism for recrystallization of amorphous phase-changeExpand
