The Pb-assisted growth of Ge nanowires (NWs) has been investigated under high and low pressure conditions via thermal decomposition of diphenylgermane. Highly crystalline Ge NWs were obtained and Pb was established as a viable growth promoter with the Pb particle being in the solid and liquid state.
