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…
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…
Tuning the flexural frequency of overhang-/T-shaped microcantilevers for high harmonics
Le Tri Dat, Chi Cuong Nguyen, Nguyen Duy Vy +1
High-harmonic (HH) frequencies in microcantilever impose several applications in precision detection thanks to the higher sensitivity of the higher modes in comparison to the funda…
Tuning the lasing threshold of quantum well exciton-polaritons under a magnetic field in Faraday geometry: a theoretical study
Le Tri Dat, Nguyen Dung Chinh, Vinh N. T. Pham +2
Polariton lasing is a promising phenomenon with potential applications in next-generation lasers that operate without the need for population inversion. Applying a perpendicular ma…
