www.sas.upenn.eduThis is a measure of a materials ability to conduct an electric current. Conductivity has SI units of siemens per meter (S·m-1) Metals, which tend to readily ionize, are good conductors of electricity. 5) Polar Covalent Bond This is a type of covalent bond. In Biological systems, polar covalent bonds are important because they

application.wiley-vch.de2/Si [7], reflecting topological compatibility to overcome the intrinsic tendency of forming wurtzite phase. In the case of highly mismatched substrates, there is usually a certain amount of zinc blende phase of ZnO separated by crystallographic defects from the wurtzite phase. The symmetry of the zinc blende
