The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Unlike laser diodes made of traditional III-V materials (III-AsP), III-Nitride laser diodes and LEDs suffer from reduced injection efficiency due to greater electron leakage [1]. The overflow of ...

The article is organized as follows. First, we briefly recapitulate the concept of one-electron molecular orbitals. We summarize the one-electron theory describing tunneling in STM junction under ...

Spin-adapted configuration state functions (CSFs) provide a compact many-electron basis for open-shell molecules. This basis is employed in one flavor of the recently introduced iterative ...
