Electrical characteristic of amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) on flexible substrate are investigated with various channel width and length. Its electrical properties according to the physical dimension of the channel are analyzed through Technology Computer-Aided Design (TCAD) simulation. Index Terms — Density of states (DOS), flexible, In-GaZn-O (IGZO),...

We have calculated free energy and vibrational entropy differences in Ni3Al between its equilibrium ordered structure and a disordered fcc solid solution. The free energy and entropy differences were calculated using the method of adiabatic switching in a molecular-dynamics formalism. The path chosen for the free-energy calculations directly connects the disordered with the ordered state. The a...

This paper describes how the concepts of Charge Neutrality Level (CNL) and Induced Density of Interface States (IDIS) can successfully explain the energy level alignment at metal-organic and organic-organic interfaces. We propose that the CNL acts as an effective Fermi level for the organic semiconductor: its partial alignment with the metal Fermi level (in the case of metal-organic interfaces)...

In this work, we proposed a novel theory of DOS for disordered organic semiconductors based on the frontier orbital and probability statistics. The has been verified by comparing with other alternatives experimental data, mobility calculated is closer to data than traditional DOS. Moreover, also provide detailed method choose parameter better use This paper contains prediction parameters, it da...

Density functional theory calculations using the generalized-gradient approximation have been carried out on the structural and electronic properties of Tin 2 and Tin clusters for n53–8 and 13. Many low-lying states, of different spins and geometries, were found for each Tin 2 and Tin species. We observed that the calculated density of states ~DOS! and the adiabatic electron binding energies fo...

We found that Sm3+ substitution in SrO SrTiO3 2 is effective in improving the Seebeck coefficient S . The S value increases notably with temperature, benefiting from an enhancement of the density of states DOS effective mass md * from 3m0 300 K to 7.5m

Objective(s): Adsorption of IMMUCILLIN-A (BCX4430) molecule on the pristine and N-doped TiO2 anatase nanoparticles were studied using the density functional theory (DFT) calculations. The adsorption energy analysis indicated that TiO2+IMMUCILLIN-A complexes including OC-substituted TiO2 have higher adsorption energy than the complexes with OT substituted TiO2, thus providing mo...

The anomalous thermodynamic properties of glasses remain incompletely understood, notably the anomalous peak in the heat capacity at low temperatures; it is believed to be due to an excess of low-frequency vibrational modes and a manifestation of the structural disorder in these systems. We study the thermodynamics and vibrational dynamics of colloidal glasses and (defected) crystals. The exper...
