Abstract

The electrical properties of chloroindium phthalocyanine (ClInPc) in a Au–ClInPc–metal sandwich structure were measured, both in a vacuum (<1.3 mPa) and at atmospheric pressure using Au, Sn and Al top contacts. In addition to current–voltage characteristics, the electroluminescence (EL) from the devices was measured and, in a vacuum, the electron emission (EE). At atmosphere all the devices show a nonlinear conduction that decays slowly over many hours. In the vacuum the Au–ClInPc–Au devices display a voltage-controlled negative differential resistance (NDR) accompanied by a peak in the electroluminescence and high field electron emission. The Au–ClInPc–Sn devices in the vacuum show an NDR with a distinct valley but with no detectable electroluminescence or electron emission. The Au–ClInPc–Al devices do not display NDR under vacuum, but show nonlinear conduction approximately 30 times greater than that observed at atmosphere.
