Strain-controlled phonon transport in van der Waals hetero-structures: a quantum study

|
By Bhanu Singh, Shubham Tyagi, Anass Sebbar, Sebastian Völz, Masahiro Nomura, Marc Bescond
| Nature Verified
Abstract We investigate phonon transport in strained van der Waals heterostructures using a first-principles nonequilibrium Green’s function (NEGF) approach. For monolayer MoS2, biaxial and uniaxial in-plane strains strongly modify phonon dispersion and transmission.

Coherent phonon transport and Anderson localization in WS 2 /MoS 2 superlattices

|
By Anass Sebbar, Shubham Tyagi, Nicolas Cavassilas, Yangyu Guo, Zhongwei Zhang, Sebastian Völz, Marc Bescond
| Nature Verified
Abstract Understanding the interplay between coherent and incoherent phonon transport is essential for designing efficient nanoscale devices. Although many studies focus on three-dimensional materials, we still lack a systematic understanding of wave-based transport and localization effects in two-dimensional systems.

Machine-learning discovery of extreme coherent thermal transport governed by motif-level order in Si-Ge superlattices

|
By Shubham Tyagi, Julian Fernandez, Natalia Seoane, Antonio García-Loureiro, Marc Bescond, Anass Sebbar
| Nature Verified
Abstract Controlling phonon-mediated heat transport in multilayer nanostructures is central to thermal management and energy-conversion technologies. Yet identifying architectures exhibiting extreme lattice thermal conductivity (κl) remains challenging due to the combinatorial complexity of interface arrangements and the high computational cost of transport simulations.
