Intersubband transition energies of a semiconductor heterostructure quantum ring with cylindrical geometry are computed considering three lowest eigenstates. Band nonparabolicity is considered to observe the change in transition energy compared with parabolic band, as well as material composition of the heterostructure is varied taking AlxGa1-xAs as an… (More)

-Transmission coefficient, eigen states and tunneling current density of a potentially symmetric quantum double barrier structure has been numerically computed using transfer matrix technique for qualitative analysis of resonant tunneling probability when realistic band structure of higher band gap material is taken into account.

Effect of tunneling resistances and tunneling capacitances on the current-voltage characteristics of single electron transistor are analytically computed assuming source and drain ends are connected by quantum dot. Steady state master equation is solved by considering tunneling mechanism a stochastic process, and free energy changes are calculated as a… (More)

-Electromagnetic wave propagation inside one-dimensional photonic crystal fiber is numerically characterized by computing V-parameter, cladding index and effective mode profiles. Dependence on these parameters on geometrical structure of the fiber reflects the design tolerance, and corresponding modal characteristics. Air-hole spacing and periodicity are… (More)
