Scientists disprove theory that reconstructed boron surface is metallic

Scientific inquiry is a hit and miss proposition, subject to constant checking and rechecking. Recently, a new class of materials was discovered called topological insulators—nonmetallic materials with a metallic surface capable of conducting electrons. The effect, based on relativity theory, exists only in special materials -— those with heavy elements —- and has the potential to revolutionize electronics.
