Abstract: The paper reports growth of germanium monoselenide (GeSe) single crystals by vapour phase technique using different transporting agents. The single crystallinity and composition of the grown samples have been verified through transmission electron microscopy (TEM) and energy dispersive analysis of X-rays (EDAX) respectively. In order to look for the possibility of phase transition, resistivity measurements have been carried out in different temperature ranges starting from 10 K. The results have indeed shown discontinuities both in the low temperature range as well as in the high temperature range. Such discontinuities in the past have been associated with possible phase transitions in GeSe. A possible explanation for the discontinuities is provided and the implications have been discussed.
