Abstract :
The synthesis of films composed of fullerene and its compounds for use in sensor electronics is demonstrated to be promising. One can see from FESEM analysis that fullerite films have a polycrystalline columnar structure with column cross-section size about 100-300 nm and clear boundaries between the columns. C60-Cu-J films have a high level of porosity and quite small resistance, which make them more convenient for application. Experiments confirm the possibility of using fullerite films in sensor electronics to produce humidity sensors. It is also possible to use the sensitivity of these films to isotropic pressure. Experiments with C60-Cu-J films have shown quite strong dependence on the pressure of different sorts of gas medium, that could be used as gas-sensitive sensors.
