We report the pH-driven formation of a dynamic 2-D porous heterostructure through assembly-disassembly switching of the stacked macrocycles of nanotubules and their subsequent spreading on the surfaces of a self-sorted sheet assembly in a hierarchical co-assembly. The 2-D ordered porous heterostructure is able to discriminate spherical C60 from flat coronene through shape selective adsorption.
A novel heterostructure was first synthesized by directly depositing photocatalytic inert ZnO2 onto facet {201} of brookite nanorods. The heterostructure thus obtained was found to show a superior photocatalytic activity under UV-light irradiation. The exceptional photocatalytic performance was due to the band-structure match between ZnO2 and brookite as well as synergic charge accumulation by ...
Graphene is a promising candidate material for high-speed and ultra-broadband photodetectors. However, graphene-based photodetectors suffer from low photoreponsivity and I(light)/I(dark) ratios due to their negligible-gap nature and small optical absorption. Here, a new type of graphene/InAs nanowire (NW) vertically stacked heterojunction infrared photodetector is reported, with a large photore...
Framework this paper we discussed an approach to manufacture a multiemitter heterotransistor. The introduced approach is a branch of recently introduced approach and based on doping by diffusion or by ion implantation of required part of heterostructure and optimization of dopant and/or radiation defects. The heterostructure should has special configuration.

We have measured the msgnetoresistance measurements of a 2D electron gas subjected to a periodic magnetic field created by the presence of type 11 superconducting stripes on the surface of the heterostructure. We observe oscillatory behaviour due to a commensurability effect between the cyclotron radius and the period of the magnetic field. The results can be understood in terms of a simple sem...
