PENGUKURAN-PENGUKURAN LlSTRIK DARI FILM MONTMORILLONITE

>

"Electrical Measurements at Montrnorilionite Films"Montmorillonite ( a clay) films dl!posited on pure titanium have been shown to give . high protection against oxidation at high temperatures. The structural investigations and the preparations of the films are reviewed briefly. The DC current-voltage characteristic measurements for several different temperatures were done to determine the activation energy of conduction and the basic transport prosess at the material. And AC conductance and capitance meaSurements over the audio fre-quency range (100Hz - 20 KHz) at room temperature were needed to determine the dielectric constant and AC conductivitY characteristics. The Poole-Frenkel effect ob-served in the material in the high field is also discussed. Zainul Astamar Tanisan
