Abstract

Semiconducting quantum wells have enabled revolutionary applications in diode lasers, IR photodetectors, and optical modulators. Recently, van der Waals (vdW) quantum wells have emerged as a promising frontier, offering inherently atomically sharp interfaces and facile integration into device structures without the constraints of lattice matching. Tunability of intersubband transitions is ...
