Abstract
Disclosed are methods and devices in which certain types of nanotubes (e.g., carbon nanotubes and boron nitride nanotubes conduct heat with high efficiency and are therefore useful in electronic-type devices.
Claims17
A nanotube phonon waveguide device, comprising:
- (a) a heat source;
- (b) a heat sink;
- (c) a nanotube attached at one end to the heat sink and at another end to the heat source, said nanotube providing a phonon path between the heat source and the heat sink, said nanotube being mechanically deformed by being bent along its length;
- and
- (d) a sensor for detecting phonon heat transmission through the nanotube.

A nanotube phonon waveguide device, comprising:
- (a) a heat source;
- (b) a heat sensor;
- (c) a plurality of carbon nanotubes attached at one end to the heat source and at another end the heat sensor, at least one of said carbon nanotubes being mechanically deformed by being bent along its length;
- (d) said heat sensor being arranged for detecting phonon heat transmission through the plurality of nanotubes;
- and
- (e) an actuator for changing distance between the heat source and the heat sensor.
