A systematic study of Gold catalyzed growth of Ge nanoneedles by PECVD at low temperatures (<4000 C) is presented. Morphology, growth rate and aspect ratio of the needles are studied as a function of power, gas flow rate and chamber pressure. Nanoneedles were grown at pre-defined positions with catalytic particles obtained by e-Beam Lithography and lift off. This opens up the possibility of using Ge Nano needles in photovoltaic, nanoelectronics and nanosensor device applications. © Springer International Publishing Switzerland 2014.
