چکیده

We explore and demonstrate quantum confinement without walls in metal-clad InAs quantum wells. We observed intersubband absorption from confined states in InAs clad with Al, Sb, Nb, W, Pt, Ag, Au, Ti or In. We found that using this novel method, we can explore the physics and chemistry at the metal–semiconductor interface; reflection, autoionization, well-width fluctuation and interface reaction. c © 2000 Academic Press

بررسی تأثیر محصورشدگی بتن در رفتار غیرخطی دیوارهای برشی بتن‌آرمه بالدار

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...

Investigation and Simulation of the Effects of Dispersion and Transmittance angles on the Solar Cells Quantum Efficiency

In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...

Electrostatic Gecko Mechanism

Nanoparticles (NPs) are ubiquitous and attach to all surfaces. Nature by providing the gecko with toe-hairs to detach NPs from surfaces has allowed electromagnetic (EM) radiation to be produced that by the photoelectric effect allows the gecko to walk on walls and ceilings by electrostatic attraction. Since attached NPs are a part of macroscopic surfaces, the atoms in the attached NPs are not u...

Effects of on-center impurity on energy levels of low-lying states in concentric double quantum rings

In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of         on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

Weak and strong confinements in prismatic and cylindrical nanostructures

Cylindrical nanostructures, namely, nanowires and pores, with rectangular and circular cross section are examined using mirror boundary conditions to solve the Schrödinger equation, within the effective mass approximation. The boundary conditions are stated as magnitude equivalence of electron's Ψ function in an arbitrary point inside a three-dimensional quantum well and image point formed by m...
