Abstract
The photothermal deflection technique has been used for contactless measurements of the thermal conductivity of thin polycrystalline diamond films grown in a dc arc discharge in different CH4/H2 mixtures. The thermal conductivity correlates inversely with amorphous sp2 carbon content in the films. Values of thermal conductivity in the range 2–5 W/cm K were obtained for ∼10‐μm‐thick diamond films deposited from gas mixtures containing methane percentages varying from 3% to 9%.This publication has 10 references indexed in Scilit:
