Photoconductive Property

Theoretical treatment of the model proposed by Giaever for his experiment on the photosensitive tunneling in superconductors is examined. New relations are derived which connect the photoconductive property of the barrier and the tunneling current. These relations are helpful to check the model and to determine the density of states for the trapped holes at the hole Fermi level.

A deposited layer of PbI 2 has been prepared by the solution technique. The yellow layers are made of hexagonal platelets parallel to the substrate plane. The photoconductive property has been investigated in the visible and near-IR bands using current measurements at different temperatures. The measurements show that an increase in the sample temperature leads to a remarkable decrease in photocurrent. The bandgap energy and type of optical transition were determined from transmission spectra, and an optical bandgap of Eg=2.32 eV for direct transition was estimated. Using the dependence of photoconductivity from temperature, a bandgap of Eg=2.32 eV was determined as well.

Polyphosphazenes containing carbazole grafted by azo nitrobenzene is synthesized by microwave method in this paper. Its structure is characterized by infrared (IR) spectroscopy and UV-visible spectroscopy. This new polymer, with both electro-optic(EO) property and photoconductive property, has unique stability and can be easily processed. Terahertz(THz) wave can be detected using the device which is made with our new polymer. The time domain waveform and frequency spectrum of the THz wave are obtained.
