A general recursion for integrals involving products of Hermite polynomials and its applications
Tran Duong Anh-Tai, Phan Quang Son, Le Minh Khang +2
This study presents the derivation of a recursive formula for integrals of products of Hermite polynomials, establishing a numerically stable scheme for their accurate evaluati…
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…
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…
Optical absorption of a CuSnS (CTS) layer trapped by metallic thin films in multilayer configuration
Le Tri Dat, Nguyen Duy Vy
Coating and reflecting thin films for energy harvesting purposes are interesting topics in both theoretical and experimental research. The thin film could help to enhance the absor…
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…
