Positron confinement in embedded lithium nanoclusters
Quantum confinement of positrons in nanoclusters offers the opportunity to obtain detailed information on the electronic structure of nanoclusters by application of positron annihilation spectroscopy techniques. In this work, positron confinement is investigated in lithium nanoclusters embedded in monocrystalline MgO. These nanoclusters were created by means of ion implantation and subsequent a...
متن کاملConfinement and Mass Gap in Abelian Gauge
First, we present a simple confining abelian pure gauge theory. Classically, its kinetic term is not positive definite, and it contains a simple UV regularized F 4 interaction. This provoques the formation of a condensate φ ∼ F 2 such that, at the saddle point φ̂ of the effective potential, the wave function normalization constant of the abelian gauge fields Zeff (φ̂) vanishes exactly. Then we st...
متن کاملConfinement-dependent below-gap state in PbS quantum dot films probed by continuous-wave photoinduced absorption.
We have measured continuous-wave (cw) photoinduced absorption (PA) spectra of PbS quantum dot (QD) films with four different sizes over a spectral range of 0.25-0.5 eV at T=10 K. The PA spectrum shows a strong asymmetric IR absorption peak (IR-PA). Both the peak position and shape of this IR-PA indicate distinct confinement dependence. Combining with results of interband transitions and Stokes ...
متن کاملQUANTUM CONFINEMENT IN CdSe NANOCRYSTALLITES
Quantum confinement increases the spacing between energy levels as the nanocrystallite size is decreased. Its qualitative features hold both for states localized near the center of a nanocrystallite and those near the surface, such as states due primarily to dangling bonds. However, different quantitative features are expected because of the different size constraints on each of these states. S...
متن کاملQuantum confinement without walls
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 reactio...
