Abstract
We have investigated the current-voltage characteristics of 7CB (4-cyano-4′-n-heptybiphenyl), 7CB:LC1 (5-(10-undecenyloxy)-2-[[[4-hexylphenyl]imino]methl]phenol) and 7CB:LC2 (5-(10-undecenyloxy)-2-[[[4-hexyloxyphenyl]imino]methl]phenol) by means of negative differential resistance and conductivity mechanism. According to differential resistance calculations, only 7CB and 7CB:LC1 exhibit N-shaped voltage-controlled NDR effect. The electrical conductivity mechanism of the related LCs has been investigated by natural logarithmic current-voltage curves. The nonlinear property of I-V characteristics has been explained by space charge limited conduction mechanism for 7CB:LC2.
