Dielectric Substrate Dependence of Thermoelectric Transport in BLG-GaAs-BLG Heterostructures
Vo Van Tai, Truong Van Tuan, Tran Trong Tai +2
We theoretically study the thermoelectric transport S in a double-layer bilayer graphene (BLG-GaAs-BLG) system on dielectric substrates (h-BN, Al2O3, HfO2). Electrons interact with…
Significant Mobility Enhancement in Coupled AlGaN/GaN Quantum Wells considering Inter-Well Distance and Asymmetric Widths
Le Tri Dat, Tran Trong Tai, Truong Van Tuan +2
We demonstrate that coupled AlGaN/GaN quantum wells with asymmetric widths ( A achieve up to 4.5 times higher mobility than single wells at optimal separation (d = 100…
Significant Enhancement of Carrier Mobility in Finite vs. Infinite Square Quantum Wells: A Comparative Study of GaAs/InGaAs/GaAs Heterostructures
Truong Van Tuan, Nguyen Dung Chinh, Tran Trong Tai +2
The geometry of quantum wells (QWs) critically influences carrier mobility, yet systematic comparisons between finite and infinite square QWs remain scarce. We present a comprehens…
Transport properties of a GaAs/InGaAs/GaAs quantum well: temperature, magnetic field and many-body effects
Truong Van Tuan, Nguyen Quoc Khanh, Vo Van Tai +1
We investigate the zero and finite temperature transport properties of a quasi-two-dimensional electron gas in a GaAs/InGaAs/GaAs quantum well under a magnetic field, taking into a…
