The contributions of inter-valence band (IVB) transitions to the dielectric function (DF) by free holes among the split-off (so), light-hole (lh) and heavy-hole (hh) bands were investigated. A model was developed to determine the DF of two p-type semiconductors, GaAs and Ge1 ySny with the Zinc-blend and Diamond crystal structures, respectively. The IVB transitions dominate the spectral range be...

fac-[Re(CO)3(dppz)] complexes of amido ligands generated in situ under basic conditions display an intense (ε = 16460 L mol-1 cm-1) absorption band between 500-700 nm which are assigned to an n(amido,RNH-) → π* (dppz) inter-ligand charge transfer band offering an extraordinarily low energy charge separating absorption with potential for imaging and energy application.

Distant and intense electronic communication between two amine sites through a porphyrin pi-spacer was quantified with inter-valence charge transfer (IVCT) band analyses.

In quest of new (”post-CMOS”) switches, in particular for ultra-low power application, the Tunnel Field Effect Transistor (TFET) [1] raised a lot of attention. The working principle of this device is the generation of electron-hole pairs by band-to-band tunneling (BTBT) between the valence band (VB) and the conduction band (CB). Thus, contrary to the common MOSFET, the source of current in a TF...

Adaptive Filtering is an important concept in the field of signal processing and has numerous applications in fields such as speech processing and communications. An Adaptive filter is a filter that self-adjusts its transfer function according to an optimizing algorithm. Because of the complexity of the optimizing algorithms, most adaptive filters are digital filters that perform digital signal...

In recent years the use of small inexpensive Xband radars for meteorological and hydrological purposes has increased significantly. Compared to the traditional C-band and S-band radars the X-band weather radar has the advantage of high temporal and spatial resolution and low financial cost; however, the trade off is attenuation due to X-band technology and short range due to the higher spatial ...

The problem of the very different E2 decay rates from the two-quasineutron K = 6 isomers in the N = 104 isotones Er, Yb, Hf, and W is investigated using the triaxial projected shell model with inclusion of multi-quasiparticle configurations. It is demonstrated that the highly K-forbidden transition from the 6 isomer to the ground-state band is sensitive to mixing with the 6 state of the γ-vibra...
