Deposition of single crystalline bismuth nanorods (Bi NRs) using a thermal evaporation method through vapor-liquid-solid (VLS) mechanism is reported here and the effect of sample cooling time on the growth of Bi \{NRs\} is investigated. Deposited Bi \{NRs\} have diameters varying from 100 to 400 nm and lengths extending to ∼3 μm in the (012) growth direction. Morphological observation indicated that the length and density of Bi \{NRs\} are strongly coupled with prolonged cooling time. A growth mechanism is suggested and discussed to describe the growth of single crystalline Bi \{NRs\} based on the morphological observations as a function of cooling temperature and time.
