CNx thin films grown by PLD at different temperatures

Carbon Nitride (CNx) thin films were grown by pulsed laser deposition using a Nd:YAG laser (1064 nm, 500mJ), in a graphite target (99.999%) on Si(100) substrate for three different temperatures 21, 50 and 200 °C, in a nitrogen atmosphere at constant pressure of 2,66 Pa. The FTIR’s analysis made to t...

Description
Summary:Carbon Nitride (CNx) thin films were grown by pulsed laser deposition using a Nd:YAG laser (1064 nm, 500mJ), in a graphite target (99.999%) on Si(100) substrate for three different temperatures 21, 50 and 200 °C, in a nitrogen atmosphere at constant pressure of 2,66 Pa. The FTIR’s analysis made to the films, revealed the presence of active modes around 1108 cm-1, 1465 cm-1, 2270 cm-1, associated with the simple, double and triple bonding of CN, respectively. Chemical composition was studied by EDX analysis, low nitrogen contents were found between 3 and 6 at%. And the mechanical properties of the films were evaluated using nanoindentation technique. The highest hardness was 14 GPa at 200 ºC substrate temperature.
