Voltage-current measurements of an amorphous indium/indium-oxide thin-film composite have yielded values for the exponent (T) describing the power-law decay of the order-parameter correlation function appropriate to the Kosterlitz-Thouless description of phase transitions in two-dimensional systems. A pronounced crossover in the characteristics at the phase-transition temperature is obtained. Theoretical expressions both above and below T₂ are verified, and a value of (T₂) =0. 23 is measured for a film with normal-state sheet resistance of 3560 / measured at 8 K.
