Abstract: A thermoelectric material includes a stack structure including alternately stacked first and second material layers. The first material layer may include a carbon nano-material. The second material layer may include a thermoelectric inorganic material. The first material layer may include a thermoelectric inorganic material in addition to the carbon nano-material. The carbon nano-material may include, for example, graphene. At least one of the first and second material layers may include a plurality of nanoparticles. The thermoelectric material may further include at least one conductor extending in an out-of-plane direction of the stack structure.

Abstract: An electrically conductive carbon nanotube-metal composite ink may include a carbon nanotube-metal composite in which metal nanoparticles are bound to a surface of a carbon nanotube by chemical self-assembly. The electrically conductive carbon nanotube-metal composite ink may have higher electrical conductivity than a commonly used metal nanoparticles-based conductive ink, and may also be used in deformable electronic devices that are flexible and stretchable, as well as commonly used electronic devices, due to the bending and stretching properties of the carbon nanotube itself.

Abstract: A method of interconnecting layers of a printed circuit board is disclosed. The method includes: forming at least one bump on a first metal layer using a conductive paste containing carbon nanotubes, stacking an insulation layer on the first metal layer such that the bumps penetrate the insulation layer, and stacking a second metal layer on the insulation layer such that the second metal layer is electrically connected with the first metal layer by the bump.
