Abstract
One-dimensional (1D) semiconductor crystal growth has attracted much attention for future nanoscale
electronic and optoelectronic devices because of their properties which are difficult to realize using bulk
materials. A review on current progress in laser-assisted bottom-up growth of many kinds of 1D
semiconductor nanocrystals and its principle growth mechanism has been described. Among many
semiconductor materials, zinc oxide (ZnO) is one of the most promising candidates for optical and
photonic devices due to excellent luminescence properties. In this article, a novel growth method of
ZnO nanocrystals, known as nanoparticle-assisted pulsed laser deposition (NAPLD) has been reviewed.
Further, a novel approach of position-controlled growth of ZnO nanocrystals by non-contact laser
irradiation without a catalyst has been discussed.
