Ultrathin Single-Crystal Diamond
Ultrathin single-crystal diamond films have controlled thickness and doping, produced by ion-implantation lift-off, epitaxial growth or precision thinning. Thickness is typically micrometer or nanometer scale. They retain ultrahigh thermal conductivity, high breakdown field, chemical inertness, strength and good optical transmission while overcoming bulk diamond brittleness and micromachining difficulty. They are transferable, bondable and readily integrated.
