[ 1 ] - رسانایی تونلی در اتصال گرافینی نرمال- عایق- ابررسانا با ساختار قرص کاربینو
We study tunneling conductance of a graphene based normal metal-insulator-superconductor (NIS) junction with Corbino disk structure. Solving Dirac-Bogolioubov- De Gennes (DBdG) equation in different regions of the junction and employing scattering approach we obtain normal and Andreev reflection coefficients of the junction. Using Blonder-Tinkham-Klapwijk (BTK) formula we calculate tunneling co...
[ 2 ] - جریان پمپی بیدررو در اتصال گرافینی نرمال- عایق- ابررسانا با ساختار قرص کاربینو
We investigate adiabatic pumping current in a graphene based normal-insulator-superconductor (NIS) junction with Corbino disk structure. The adiabatic pumping current is generated by two electrostatic potentials, oscillating periodically and out of phase, applied to the insulating and superconducting regions. Using the extended Brouwer’s formula for the adiabatic pumping current, which is based...
