Thermal conductivity in radial and planar Si/SiOx hybrid superlattices

Thermal conductivities through radial and planar Si/SiOx hybrid superlattices are substantially reduced -- putting forth a novel efficient way of managing phonon transport in Si-based devices.

Thermal conductivity of mechanically joined nanomembrane superlattices

Hybrid superlattices consisting of a large number of nanomembranes mechanically stacked on top of each other are fabricated by a roll-up and press-back technique.

When Silicon becomes a better thermal insulator than glass…

Introducing Ge nanostructures into single-crystalline Si leads to thermal conductivities which are lower than any other SiGe alloy, amorphous Si  and even glass.
