摘要： Transition-metal monosilicide RhGe has been reported to exhibit weak itinerant ferromagnetism, superconductivity, and topological properties. In this study, we report the high-pressure growth of high-quality RhGe single crystals up to millimeter size using a flux method. Transport measurements reveal metallic behavior in RhGe from 2 K to 300 K with Fermi liquid behavior at low temperatures. However, no superconductivity was observed with variations in the Ge composition. Magnetic characterizations indicate that RhGe exhibits paramagnetic behavior between 2 K and 300 K. The high-quality and large-size RhGe single crystals pave the way for further investigation of their topological properties using spectroscopic techniques.
