• The absolute thermopower, Theta, of Ti3SiC2 over the temperature range 300 to 850 K is investigated. Theta and electrical resistivity, rho, were measured simultaneously on the same specimen of single-phase Ti3SiC2. It is shown that Theta is practically zero within +/- 0.22 micro-V/K in the temperature range examined. It is argued that Theta should remain zero even outside this range. It is inferred that the thermoelectric contributions by electrons and holes delicately cancel each other out over a wide temperature range. The concentration, mobility, and heat of transport values of the electrons are identical to those of the holes over the temperature range investigated. (CSA)
