Quantum Cascade Structure

In this work, we calculated the characteristics of a two-dimensional plasmon amplified by an active medium based on a terahertz quantum-cascade structure. It is shown that for realistic parameters of GaAs/AlGaAs structures with quantum wells (mobility 2×105 cm2V-1s-1 at an electron concentration of 5×1011 cm-2 and at temperatures up to 77 K), the gain of a two-dimensional plasmon can reach 1500 cm-1 for frequency 2.3 THz. In addition, due to the strong localization of the plasmon electric field near the quantum well, only a few cascades of the active medium are required for amplification.

It is found that the biaxial strain, electric field and interlayer distance can effectively modulate the electronic structure and magnetic properties of two-dimensional van der Waals heterostructures.
