15/8/2013· Abstract. This paper reports on the measurement of the thermal coefficient of Young''s modulus of both single crystal silicon and 3C silicon carbide over the temperature range spanning 200–290 K. The thermal coefficients were determined by monitoring the change of resonance frequency of micro-cantilevers as their temperature was reduced.
