A convenient hydrogen-assisted thermal evaporation method to synthesize nano-ribbons of the semiconductor ZnS is introduced. As such, the synthetic reaction is carried out in a quartz tube furnace using high-purity Ar premixed with 5% H2 as carrier gas at 1100°C and sphalerite ZnS as source. The results presented a new compound semiconductor nanoribbon, different from silicon or oxides, which may provide a guide for obtaining other non-oxide semiconductor nanoribbons.
