In this paper we study the distribution of scattering resonances for a multidimensional semi-classical Schrodinger operator, associated to potential well in an island at energies close maximal one that limits separation and surrounding sea.
we discuss the asymptotic behaviour of solutions for the nonlocal quasilinear hyperbolic problem of kirchhoff type [ u_{tt}-phi (x)||nabla u(t)||^{2}delta u+delta u_{t}=|u|^{a}u,, x in mathbb{r}^{n} ,,tgeq 0;,]with initial conditions $u(x,0) = u_0 (x)$ and $u_t(x,0) = u_1 (x)$, in the case where $n geq 3, ; delta geq 0$ and $(phi (x))^{-1} =g (x)$ is a positive function lying in $l^{n/2}(mathb...
In this letter we introduce a quantum well infrared photodetector ~QWIP! structure, which we refer to as the quantum grid infrared photodetector ~QGIP!. In an ideal structure, a grid pattern with very narrow linewidth is created in the QWIP active region to achieve lateral electron confinement, thereby improving its absorption as well as transport characteristics. In order to realize this detec...
