Quantum wellAdmittance spectroscopyActivation energySiGe/Si quantum wells (QWs) with different Boron doping concentrations were grown by molecular beam epitaxy (MBE) on p-type Si(100) substrate. The activation energies of the heavily holes in ground states of QWs, which correspond to the energy ...
1 An electron in a square quantum well is the classic particle-in-a-box of basic quantum mechanics. The electron cannot have just any energy inside the well: rather, it is constrained to reside in certain discrete energy levels, i.e., its energy is quantized. These allowed energy levels,...
which offers the possibility of tuning band structure and enables the transition from semimetals to semiconductors. For example, when the quasi-1D electron gas for the Bi nanowires is confined inside a cylindrical potential well, the energy levelsEijthat electrons (and also holes)...
A coherently prepared asymmetric double semiconductor quantum well (QW) is proposed to realize parity-time (PT) symmetry. By appropriately tuning the laser fields and the pertinent QW parameters, PT-symmetric optical potentials are obtained by three diff
In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the material may be a solid, liquid, or gas; and the released particles may be ions (electrically charged atoms or molecules) as well as electrons. The phenomenon was ...

Reducing trial-and-error lab processes and accelerating discovery of new materials are only possible if materials scientists can derive higher-level spectral, thermodynamic, and other properties from ground-state energy levels described by the Schrödinger equation. The problem is that none of today’...
To successfully execute this, Alice would need to be able to store all the photons for a significant amount of time as well as measure them with near perfect efficiency. This is because any photon lost in storage or in measurement would result in a hole in her string that she would have...
The thin, 0.8-nm well serves as the upper lasing level, while the 3.0-nm well serves as the lower lasing level. It should be recalled that the thickness of each quantum well determines the allowed energy levels, i.e., thin layers generate high-lying energy levels, while thicker layers ...
