“…The addition of organic and inorganic materials has already been used to tailor electrical and optical properties of silicon nanostructures. 6,12,25,26 TiO 2 NPs are found in three phases, anatase, rutile, and brookite. Anatase phase is formed at low temperature $450 C and rutile phase is formed at $650 C. Room temperature synthesis of TiO 2 NPs in this study yielded anatase phase of TiO 2 NPs.…”

We investigate carrier transport properties of silicon nanowire (SiNW) arrays decorated with TiO2 nanoparticles (NPs). Ohmic conduction was dominant at lower voltages and space charge limited current with and without traps was observed at higher voltages. Mott’s 3D variable range hoping mechanism was found to be dominant at lower temperatures. The minimum hopping distance (Rmin) for n and p-SiNWs/TiO2 NPs devices was 1.5 nm and 0.68 nm, respectively, at 77 K. The decrease in the value of Rmin can be attributed to higher carrier mobility in p-SiNWs/TiO2 NPs than that of n-SiNWs/TiO2 NPs hybrid device

“…Remaining proposed diodes 2(4) energy value 0 eV stage transmission coefficients also 0, and interesting observation is only positive energy time only transmission occurs whereas negative energy applied to diode structures no transmission says that diode 2(4) acts like a conventional semiconductor diode. It is notable that HOMO energy closer to the Fermi energy during positive bias and far away from Fermi energy in the negative bias applied [8,9].…”

The electronic transport properties of electrons in a molecules are observed by using Non equilibrium Green's function(NEGF). We present a extremely through and careful computational approach well ordered method to do a framework analysis of donor (CH3) and acceptor (CN) molecules connected between the Au(111) contacts, and also observed current progress through molecular devices depends on number of bonds or not. Such observations implementation through not possible by standard quantum chemistry soft wares. The results shows I-V characteristics, Transport spectrum and Transport analysis can effectively tune the molecules works like a conventional semiconductor based diodes, these results invoke to design the logic gates and logic circuits.

“…Coating other material on the backbone nanowires is the most facile and common way to synthesize coaxial nanowires [14]. Coaxial MoO 3 /PTh [35], MnO 2 /CNT [36], and Polymer/Si [37] nanowires have exhibited superior advantages in terms of electrical conductivity, mechanical stability, and electrochemical performance. Moreover, triaxial nanowires with conductive coating and increased active sites may further improve the cycling and rate performance [38].…”

Green energy has been increasingly demanded with the rapid development of economy and population. The electrochemical performance of energy storage devices could be improved by using nanomaterials, but their fast capacity fading is still one of the key limitations. The intrinsic reasons of capacity fading need to be further understood. Here, we review some single nanowire electrode devices designed as a unique platform for in situ probing the direct relationship between electrical transport, structure, and other properties of the single nanowire electrode before and after cycling. It is found that the conductivity decrease of the nanowire electrode and the structural change during electrochemical reaction limited devices' lifespan. Some strategies, such as prelithiation, conductive coating and structural construction, are designed and used to restrain the conductivity decrease and structural disorder/destruction, which improve the lifespan and rate capability of energy storage devices. Further, the stand-alone rechargeable nanobatteries built up by nanowires are able to meet the needs of energy storage in self-powered nanosystems.
