## Description

- description: In this study, we propose stacked GaAs 2DEG thermoelectric generator
    (TEG), which has a number of stacked channel structures for low electrical resistance.
    Our GaAs 2DEG TEGs with channels formed in triangular well exhibit ultrahigh thermoelectric
    power factor. In addition, the interfaces of the stacked 2DEG intensify phonon
    scatterings, resulting in the reduction of thermal conductivity. The stacked 2DEG
    TEGs exhibit 9 times higher sheet electrical conductivity than the unstacked 2DEG
    one, resulting in ~7.5 times higher output power of stacked 2DEG TEGs (5.1 nW)
    than that of unstacked 2DEG ones.
