The quantum-confined Stark effect (QCSE) describes the effect of an external electric field upon the light absorption spectrum or emission spectrum of a quantum well (QW). In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands.
11. Okt. 2018 · The quantum-confined Stark effect (QCSE) is an established optical modulation mechanism, yet top-performing modulators harnessing it rely on costly fabrication processes.
The quantum-confined Stark effect (QCSE) causes strong polarization in InGaN MQWs when the active GaN layers are grown in the c -axis direction and are thicker than 3 nm. This reduces the efficiency of the LEDs and was the motivation behind the search for semipolar or nonpolar GaN LEDs.

31. Mai 2022 · The two frequently observed phenomena, photoluminescence (PL) blinking and quantum-confined Stark effect (QCSE)-induced spectral diffusion, are not conducive to the applications of colloidal quantum dots (QDs). It remains elusive how these two phenomena are linked to each other.
