quantum well

[¦kwän·təm ′wel]
(electronics)
A thin layer of material (typically between 1 and 10 nanometers thick) within which the potential energy of an electron is less than outside the layer, so that the motion of the electron perpendicular to the layer is quantized.

Multiple quantum wells (MQW), extremely thin layers of Group III-V materials, are used as the gain medium in VCSELs and can be strained to improve VCSEL performance.
The researchers conducted their study with the aim of 'analyzing and evaluating the internal electric fields' effects on the performance of single and multiple quantum wells based on (GaN/InGaN) nano-structured nitrogen containing strain-balanced semiconductors'.
The VCSEL is actually a microcavity created by sandwiching indium gallium nitride multiple quantum wells (or blue LEDs) between two nitride- and oxide-based reflectors.
