Abstract

The effect of trapping centers on the conductivity of amorphous 2,4,7-trinitro-nine-fluorenone (a-TNF) was investigated by space charge limited current (SCLC), thermally stimulated current (TSC), and transient photoconductivity methods. It is found that electron traps in a-TNF have a smoothly varying distribution centered at about E_t equals 0.29 +/- 0.04 eV with a dispersion parameter (sigma) equals 0.11 +/- 0.02 eV. The true activation energy at room temperature is E_a equals 0.45 +/- 0.03 eV. The zero-field extrapolated activation energy is E_ao equals 0.65 +/- 0.02 eV. It was suggested that the transport of charge carriers in a-TNF was controlled by traps. The concentration of traps and drift mobility of electrons was evaluated.
