Effect of screening on Seebeck coefficient in bilayer graphene/AlGaAs electron gas
Vo Van Tai, Nguyen Duy Vy, Truong Van Tuan +1
The knowledge of Seebeck coefficient is a key factor in optimization of thermoelectric materials and finding right applications for it. A high sensitivity to structural change make…
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…
Competition between heating and cooling effects in an optomechanical oscillator using a squeezed field
Vinh N. T. Pham, Chu Manh Hoang, Nguyen Duy Vy
Squeezed light is a useful phenomenon that can be exploited to improve the sensitivity of specific classes of detectors based on optomechanical effects. Recently, there has been si…
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…
Revealing Modeshape Complexity and Sensitivity in Torsional Vibrations of Microcantilevers with Overhang- and T-shaped Geometries
Le Tri Dat, Nguyen Duy Vy
The torsional vibration of atomic force microscope (AFM) cantilevers is critical for high-sensitivity measurements, yet existing models for width-varying cantilevers often rely on…
