Through detailed analysis combining simulation and experimental measurements, several kinds of parasitic capacitances dragging the actual speed of carbon nanotube field-effect-transistor integrated circuits (CNT FET ICs) are identified one by one. Various optimized schemes are suggested and demonstrated to minimize the effect of parasitic capacitances, and thus improve the speed of CNT ICs.

Copper nanowires have been embedded into pre-coated poly-(3,4- ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on polymer films by solution processing to form flexible transparent conductive electrodes, which can be used as anodes for bulk heterojunction solar cells, giving a power conversion efficiency of 1.4%.

A general route has been developed for the direct synthesis of self- organized metal每semiconductor epitaxial graphene layers. Using a off-axis 4H-SiC(0001) substrate, the formation of a periodic arrangement of monolayer graphene on planar (0001) terraces and Bernal bilayer graphene on (112 __ 0) nanofacets of SiC is possible in a one-step process.
