In this talk\, I will discuss the discovery of two different intermetallics with this method: S mMnBi2\, a candidate for topological semimetals\, and MM’2Zn20\, a candid ate for thermoelectric materials.\n\n\nIn topological materials\, the bul k is a bad conductor while the surface states are metallic with high mobi lity. The surface is also topologically protected\; basically meaning tha t impurities have no effect on the conductivity. A plethora of materials have been discovered and I will talk about the growth and structure of Sm MnBi2 and compare it to similar compounds.\n\n\nThermoelectric materials are appealing due their ability to directly convert between heat and elec tricity. The main issue is that the physical parameters to determine ther moelectric performance work against one another. For achieving the optimu m performance\, hindering lattice vibration by forming cage structures in which heavy atoms can rattle is a plausible way. I will talk about the g rowth and structure of cage-structured MM’2Zn20 compounds.
