Terahertz Plasma Oscillations in Nanotransistors,s work we give an overview of our recent experimental results concerning this effect. The first observation of the resonant THz detection was demonstrated on 150 nm gate length GaAs FET. The most important recent result concerning the detection is a very strong (two orders of magnitude) enhancement

High-Intensity THz Radiation From a Large Interdigitated Array Photoconductive Emitter,riod of this structure optical excitation is inhibited. Thus carrier acceleration is unidirectional over the whole device area and the emitted THz radiation interferes constructively in the far field. Excitation with amplified laser pulses leads to THz amplitudes of 6 kV/cm. Saturation of the emissi

Broadband Terahertz Emission From Ion-Implanted Semiconductors,e an increase in the spectral width of terahertz radiation at greater ion damage, which we attribute to the ultrafast capture of photoexcited carriers. Results from a three-dimensional carrier dynamics simulation support this explanation.

THz Collective Real-Space Oscillations of Ballistic Electrons in Wide Parabolic Potential Wells: anillate across the well instead of performing the intuitively expected unidirectional relaxation towards the bottom of the well. Surprisingly, the coherence of the periodic electron motion is maintained despite multiple phonon scattering events. This novel transport regime is predicted by Monte Carlo

A fully self-consistent Schrödinger - Poisson analysis based on the scattering rate equation approach was employed to simulate the above-threshold electron transport in the devi

Although in this context the evaluation of teachers has been presented as one of the most important links to transform educational systems, developing this type of eva

However, it was not until the implementation of the . (LRM, Teacher Reform Law) of 2012 that teacher evaluation policies were clearly and more systematically implemented. The LRM unified all the teachers in the publi

In 2007, the District of Columbia passed the Public Education Reform Amendment Act (PERAA) that transitioned DCPS to mayoral control and led to a slurry of reforms—most contentious of which was IMPACT. IMPACT’s design was informed by rese

Inductive analysis of semi-structured interview data with 24 novices revealed influences of social and cultural aspects of the local community on their learning at the workplace. We found that novices’ experience of their status am
