Optically transparent electrode diamond thin films

In addition to these, there has been considerable amount of research danonstrat-ing the use of NCD thin film in packaging and thermal applications [47]. Active devices, like transistors, have been mounted on diamond carriers thereby improving their performance due to better thermal management. The high thermal conductivity exhibited by thin film diamond has been a positive impact in packaging approaches in the MEMS devices, as well. Furthermore, NCD has been used for many optical applications to fabricate resonators [48], two-dimensional photonic crystals [49], UV transparent electrodes on SiC [50] and in some sensor applications [51],... 

Another electrode form is a thin film deposited on an optically transparent nondiamond substrate, such as undoped Si for IR or quartz for UV/Vis spectroelectrochemical measurements. Diamond deposition on Si for IR OTEs is rather straightforward and involves growth conditions similar to those described above. The resulting films are 2-4 gm thick with micrometer-sized grains of diamond randomly oriented over the surface. Deposition of thin films of diamond on quartz is a little more involved [118]. Figure 22 shows an optical image of a diamond/quartz OTE. The film has a blue hue to it due to the boron doping level. It is...
