DC CONDUCTION MECHANISM IN GLYCINE

The dc conductivity of glycine was measured to study the mechanism of electrical conduction. The current was measured using Kiethley's Elect rometer 600 B by applying dc electric field in the range 0.9-7.5 kV/cm at eight thermostatically controlled temperatures in the range 313-38 3 K. Results are presented in the form of I-V characteristics and anal ysis has been made by interpretation of Poole-Frenkel, Fowler-Nordheim , Schottky, In(J) versus T plots, Richardson and Arrehenius plots. Res ults as analyzed in terms of different mechanisms suggest that Schottk y-Richardson mechanism is primarily responsible for the observed dc co nduction.
