Today, his team is one of very few to do experiments on the thermal transport properties of quantum electronic circuits. Their work paves the way for new methods of probing states of matter and a better understanding of their "non-conventional" aspects, and will be of interest in future in the branch of engineering dealing with "strongly correlated" materials.

(b) Direction perpendicular to the ladder. Here, the thermal transport anisotropy of BP nanoribbons is probed by an electron beam technique. Direct evidence is provided that the origin of this anisotropy is dominated by the anisotropic phonon group velocity, verified by Young's modulus measurements along different directions.

Thermal and thermoelectric transport in quantum systems. Thermal and thermoelectric transport measurements in quantum engineered materials platforms can reveal physical behaviors hidden to purely electrical transport. Thermal conductivity measured with Johnson noise thermometry can probe the details of electronic scattering and interactions, and thermopower measurements provide a unique signature of the entropy per particle.

Introduction. In conventional electronic devices such as field-effect transistors (FETs) or diodes, the size of the device is usually quite large, so that the wave nature of the electron or its discrete charge do not influence the behavior of the device. Furthermore, all individual Electrons in graphene can show diffraction and interference phenomena fully analogous to light thanks to their Dirac-like energy dispersion. However, it is not clear how this optical analogy persists in nanostructured graphene, for example, with pores. Nanoporous graphene (NPG) consisting of linked graphene nanoribbons has recently been fabricated using molecular precursors and bottom-up 2021-03-15 · "Quantum size effects provide an excellent opportunity for engineering materials with novel thermal properties suitable for energy conservation and conversion technologies such as 2019-11-30 · (a) Interaction between microstructure and heat generation.

Significance and Impact Recently, in basic research, thermal transport has been used as a probe of otherwise elusive states of matter such as strongly interacting quantum Hall systems 3, and the phonon spectrum in Abstract Quantum spin liquids(QSL) have fascinated physicists for nearly half a century since Anderson first introduced this concept with his resonating-valence-bond(RVB) idea in 1973. Although many progresses had been made, more challenges emerge from both theoretical and experimental perspectives.
