The Interaction of HCN Gas on the Surface of Pristine, Ga, N and GaN-Doped (4,4) Armchair Models of BPNTs: A Computational Approach

In this research, the interactions of HCN gas with pristine, Ga-, N- and GaN-doped of boron phosphide nanotube (BPNTs) were investigated by using density function theory (DFT). The structure, electrical and NQR parameters, quantum descriptors involving energy gap, global hardness, global softness, electrophilicity, electronic chemical potential and electronegativity were calculated. The adsorpt...

و چاه کوانتومی چندتائی InxGa1-xN بررسی مدهای اپتیکی آلیاژ در ناحیه فروسرخ دور In0.5Ga0.5N/GaN

Optical properties of InxGa1-xN alloy and In0.5Ga0.5N/GaN multi quantum wells have been investigated in the region of far infrared. Far-IR reflectivity spectra of In0.5Ga0.5N/GaN multi quantum wells on GaAs substrate have been obtained by oblique incidence p- and s-polarization light using effective medium approximation. The spectra and the dielectric functions response give a good informa...

Doping and electrical properties of amorphous silicon carbon nitride films

Electrical properties and annealing behaviour of undoped and doped amorphous silicon carbon nitride (a-SiC N ) thin films, x y deposited by ion beam sputtering techniques, have been studied. Doping of the a-SiC N thin films with magnesium (Mg), and x y phosphorous (P) was carried out by ion implantation techniques, and subsequent annealing effect on the electrical conductivity (s) and activatio...

Sensing Performance of Sc-doped B12N12 Nanocage for Detecting Toxic Cyanogen Gas: A Computational Study

Adsorption of cyanogen molecule on the surface of pristine and Sc-doped B12N12 nanocage is scrutinized using at DFT calculations to investigating its potential as chemical nanosensors. The results show that cyanogen is weakly adsorbed on the pristine B12N12 and consequently its electrical properties are changed insignificantly. In order to improve the...
