Experimental evidence of thermoelectric amplification of acoustic waves in nickel

We present experimental results on the detection of an exponentially growing acoustic signal in nickel as a function of the temperature gradient applied to the sample. These results are interpreted as resulting from the onset of the thermoelectric amplification of acoustic waves in the sample.
