Topological insulator is a recently discovered class of material with topologically protected surface state. YbB6 is predicted to be moderately correlated Z2 topological insulator similar to SmB6. Here, I experimentally test the resistance property of bulk YbB6 to verify its topological property. By changing the thickness of YbB6, I found out that although the data curves did not completely conform to the theory of topology, the experimental observation to the overall trend showed a similar topological phenomenon.
