There has been measured the crystallization temperature of supercooled Bi particles versus their size in the 3–100 nm range in island films on amorphous carbon substrates. Crystallization temperature is found to decrease with particle size decreasing and the supercooling vanishes for particles of 2–3 nm in diameter. The results obtained are analyzed in the frame of the classic theory of crystallization.
