Thermoelectric properties of finite two-dimensional quantum dot arrays with band-like electronic states

The thermal power (PF = S2Ge) depends on the Seebeck coefficient (S) and electron conductance (Ge). enhancement of Ge will unavoidably suppress S because they are closely related. As a consequence, optimization PF is extremely difficult. Here, we theoretically investigated thermoelectric properties two-dimensional quantum dot (QD) arrays with carriers injected from electrodes. Lorenz number 2D QD in resonant tunneling procedure satisfies Wiedemann-Franz law, which confirms formation minibands. When miniband center far away Fermi level electrodes, transport thermionic-assisted (TATP). In this regime, band-like situation atom-like can happen simultaneously. We have demonstrated that an increasing electronic states not TATP.
