the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

We investigate the phase diagram of spinless bosons with long range (variant 1/r(3)) repulsive interactions, relevant to ultracold polarized atoms or molecules, using density matrix renormalization group. Between the two conventional insulating phases, the Mott and density wave phases, we find a new phase possessing hidden order revealed by nonlocal string correlations analogous to those charac...

This paper examines charge transport by tunneling across a series of electrically insulating molecules with the structure HS(CH2)4CONH(CH2)2R) in the form of self-assembled monolayers (SAMs), supported on silver. The molecules examined were studied experimentally by Yoon et al. (Angew. Chem. Int. Ed. 2012, 51, 4658-4661), using junctions of the structure AgS(CH2)4CONH(CH2)2R//Ga2O3/EGaIn. The t...

The insulating granular film of Co±Al±O consists of nano-scaled magnetic granules of cobalt embedded in amorphous alumina. This kind of system shows a large tunnel-type giant magnetoresistance (TMR) effect at room temperature when its composition and microstructure are appropriate [1]. Similar to the other fine magnetic particle systems, the grains in this film may correlate each other. However...

In this paper, we study the effect of insulating and non-insulating cost allocations on internal trade in a model of incomplete information. From the perspective of firm-wide profit, the allocation scheme that results in the least amount of rationing (forgone profitable trade) is the optimal one. If one thinks of internal trade as a form of cooperation, one might expect non-insulating allocatio...

This work analyzes and discusses analytically a method of controling the insulating properties of an assembly. It establishes the feasibility of utilizing gas layers within the insulating assembly separated by flexible soft seals. The volumetric thermal expansion of the main gas layers within the insulating assembly are determined taking into consideration the variation in the gas pressure due ...

Optical properties of ultrathin layers (<50 A) of Au and Pb quench condensed on amorphous germanium (alpha-Ge) have been measured in situ at 10 K. The development of these films from an insulating state to a metallic state is traced as a function of the film thickness as well as the sheet resistance, R(square). Of particular interest is the regime of R(square) near 3000 Omega where there is an ...

Recent experiments on short MoGe nanowires show a sharp superconducting-insulating transition at the universal resistance R(Q)=h/(4e(2)), contrary to the expectation of a smooth temperature dependence of the resistance for such Josephson-like systems. We present a self-consistent renormalization-group treatment of interacting quantum phase slips in short superconducting wires, which reproduces ...
