(Nanowerk News) Diamond has long been a fascinating material from jewels to artificially made thin films. It has long been considered as an ideal candidate for electronic device applications due to its highest thermal conductivity and robustness to use in diverse conditions.
To revolutionize diamond-based electronics, the usually insulating diamond should be fabricated or doped as n-type conducting nature. A few years ago, nitrogen doping at high temperature of about 800°C has been suggested to create n-type conducting nature in the ultrannaocrystalline diamond (UNCD), which own similar properties as diamond.
Further, they showed the fabrication of freestanding UNCD films, which could be easily bonded to substrates for diverse applications. They foresee a great potential for these findings and the bonded freestanding films on to flexible substrates to be used in flexible diamond based electronic devices.
