Thin is cool: researchers unveil the excellent heat dissipation properties of layered semiconductors down to the monolayer !

The increasing demand for extremely small components and devices has led scientists to search for new materials that could best meet these needs. Two-dimensional layered materials (2D materials) – which can be as thin as one or a few atomic layers and are strongly bonded only in the in-plane direction – have attracted the attention of both academia and industry, and do not cease to amaze with their peculiar and remarkable properties. Among them, transition metal dichalcogenides (TMDs) are promising for a variety of electronic, optoelectronic and photonic applications.

 A study published in “Advanced Materials” reveals the thermal transport properties of ultrathin crystals (made of just one or a few layers) of molybdenum diselenide, a two-dimensional (2D) material of the transition metal dichalcogenide (TMD) family.
