Switching effect in Cu:TCNQ charge transfer-complex thin films by vacuum codeposition

Photovoltaic effect in CuTCNQ organic thin films

An experimental study was carried out of photovoltaic effects occurring in the structure Cu/CuTCNQ/ITO(A1). Prototype devices were fabricated by growing CuTCNQ organic thin films directly on a copper substrate and then laying the semitransparent electrodes (glass/ITO or glass/Al) on the CuTCNQ/Cu. By choosing appropriate conditions for formation of the film in the liquid phase, for example solu...

Investigation of resistive switching in anodized titanium dioxide thin films

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...

Ultrafast charge carrier relaxation and charge transfer processes in CdS/CdTe thin films.

Ultrafast transient absorption pump-probe spectroscopy (TAPPS) has been employed to investigate charge carrier relaxation in cadmium sulfide/cadmium telluride (CdS/CdTe) nanoparticle (NP)-based thin films and electron transfer (ET) processes between CdTe and CdS. Effects of post-growth annealing treatments to ET processes have been investigated by carrying out TAPPS experiments on three CdS/CdT...

Influence of the vacuum interface on the charge distribution in V2O3 thin films

The electronic structure of V2O3 thin films is studied by means of the augmented spherical wave method as based on density functional theory and the local density approximation. We establish that the effects of charge redistribution, induced by the vacuum interface, in such films are restricted to a very narrow surface layer of ≈15Å thickness. As a consequence, charge redistribution can be rule...
