• Transport of holes through beta-carotene glass was studied using a transient photoconductivity technique. The mobility is measured to be 1.5×10^<-3> cm^2/V sec at 21℃ and 10^4 V/cm. The motion of carriers can be represented by transit time T_r, which means the time necessary for a charge carrier to travel from the front electrode to the counter-electrode of the sample. The inverse transit time (T_r)^<-1> is found to vary with temperature T in the form of exp (-ε_0/kT), with ε_0=0.22 eV, and to vary with electric field E in the form of exp (α_cE^<1/2>) with α_e=2×10^<-10> F/m at 1 KHz. Using the Poole-Frenkel theory, the coefficient of E^<1/2> in exp (α_tE^<1/2>) is estimated to be α_t=1×10^<-3> (m/V)^<1/2>. The observed α_e agrees approximately with the value of estimated α_t. Therefore, it is concluded that the transport of charge carrier is mainly controlled by the Poole-Frenkel effect.
