Three 1-(anthracene-9-ylmethyl)-3-isopropyl-imidazol-2-thione Zn(II) halide complexes (1-3) and one 1-(anthracene-9-ylmethyl)-3-isopropyl-imidazol-2-selone dichloride complex (4) were synthesized characterized. Complexes 2, 3, 4 exhibited distorted tetrahedral geometries, while 1 adopted a regular geometry. All these displayed emission in the crystalline state, with 3 emitting yellow region blue region, 2 gave bluish-green emission. The ligands L1 L2, however, showed no solution state....
We study the effect of asymmetric potential profile on electron mobility µ a double quantum well (DQW) structure. In DQW, along with confinement effect, coupling subband states between wells further splits energy levels thereby acting as an additional degree freedom to regulate structure properties. introduce asymmetry (1) in doping concentrations barriers, (2) shape wells, i.e., taking one square and another parabolic (3) by applying electric field F profile. calculate low temperature...
We analyze the asymmetric delta-doping dependence of nonlinear electron mobility μ GaAs|In x Ga 1-x As double quantum-well pseudo-morphic modulation doped field-effect transistor structure. solve Schrodinger and Poisson's equations self-consistently to obtain sub-band energy levels wave functions. consider scatterings due ionized impurities (IMP), alloy disorder (AL), interface roughness (IR) calculate for a system having occupancy, in which inter-sub-band effects play an important...
