Question
For a gas acting as one of these materials, the secondary emission coefficient, pressure, and gap distance are put into Paschen’s law to calculate breakdown voltage. Bismuth antimonides exemplify a type of these materials with symmetry-protected surface states, their topological variety. A sphere made of one of these materials has excess charges pinned to their initial position in Gauss’s law problems. These materials have a large band gap. A polarizable one of these materials can increase the capacitance of a parallel-plate capacitor by acting as a dielectric. These materials have high resistivity and include rubber and plastic. For 10 points, name these materials which do not conduct electricity. ■END■
