Isolator (material) – Wikipedia
Bandgapet i isolatorer Isolator eller oledare [1] är ett material som inte leder elektrisk ström, till skillnad från en elektrisk ledare eller halvledare.Isolatorer brukar ha en dålig värmeledningsförmåga (termisk isolator).Ledningsbandet i isolatormaterial är helt tomt på elektroner, vilket medför att inga elektroner kan transporteras genom materialet.
