Pseudospins revealed through the giant dynamical Franz-Keldysh effect in massless Dirac materials

Autor: Youngjae Kim

Publikováno v: npj Quantum Materials, Vol 9, Iss 1, Pp 1-7 (2024)

Abstract The dynamical Franz-Keldysh effect, indicative of the transient light-matter interaction regime between quantum and classical realms, is widely recognized as an essential signature in wide bandgap condensed matter systems such as dielectrics

Subcycle control of valley-selective excitation via dynamical Franz-Keldysh effect in WSe$_2$ monolayer

Autor: Yamada, Shunsuke, Yabana, Kazuhiro, Otobe, Tomohito

This study performed first-principles calculations based on the time-dependent density functional theory to control the valley degree of freedom relating to the dynamical Franz-Keldysh effect (DFKE) in a monolayer of transition metal dichalcogenide.

In this paper we report on a low energy consumption CMOS-compatible plasmonic modulator based on Franz-Keldysh effect in germanium on silicon. We performed integrated electro-optical simulations in order to optimize the main characteristics of the mo
