The atomic and electronic structures of semiconductor heterostructures including steps, misfit dislocations and interface disorder are studied by using the densityfunctional tight-binding (TB) method. Atomic structures of misfit dislocations both edge type 1/2 <110> (001) and 60°dislocations in the semiconductor heterostructures, like Si-Ge superlattices and GaAs/Si systems are studied by using...

We propose to replace Ga in (Ga,Mn)As with Li and Zn as a route to high Curie temperature, carrier mediated ferromagnetism in a dilute moment n-type semiconductor. Superior material characteristics, rendering Li(Zn,Mn)As a realistic candidate for such a system, include high solubility of the isovalent substitutional Mn impurity and carrier concentration controlled independently of Mn doping by ...

Extending the ionic conductivity is pre-requisite of electrolytes in fuel cell technology for high-electrochemical performance. In this regards, introduction semiconductor-oxide materials and approach heterostructure formation by modulating energy bands to enhance conduction acting as electrolyte cell-device are employed. Semiconductor (n-type; SnO2) plays key role introducing into p-type SrFe0...

The semiconductor properties of a carbon nanotube film can be changed from p-type to n-type by molecular wrapping oxyethylene surfactants.

Directional crystallization from the melt has been used as a tool to grow parallel crystalline stripes of p- and n-type molecular semiconductors. To start, phase behavior 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT-C8): tetracyanoquinodimethane (TCNQ) blends (molar ratio 20:1 1:1) investigated by variable-temperature X-ray diffraction, differential scanning calorimetry, polarized...

In the last decades an important number of research papers published on nano chip electrode and cathode electrochromic materials. Tantalum (Ta) with so high melting point can be as a good candidate for the future of nano chip devices. However, its surface has not enough trap centers and/or occupation states, so nitrogen ions exposed on Ta surafce, may solve this problem. For this purpose, in th...

Recently, we developed a computational model that allowed us to study the influence a semiconductor membrane has on a DNA molecule translocating through a nanopore in this membrane. Our model incorporated both the self-consistent Poisson-Nernst-Planck simulations for the electric potential of a solid state membrane immersed in an electrolyte solution together with the Brownian dynamics of the b...
