Charge-Injection devices construction

A Charge Injection Device (CID) camera system has been designed and constructed for use as a detector for atomic emission spectrometry. 

PPV-based devices are commonly constructed in a multilayer structure in which the polymer film is sandwiched between charge injection electrodes. For this reason, the polymer/electrode interface plays an important role on the performance of the devices and will be discussed for different classes of materials in the next sections. 

The results obtained for the solar cell discussed above suggest a strong interaction between the chromophore and the metal oxide layer, a large surface area, thus yielding large absorbances, and an efficient charge-separation upon injection. Several studies have indeed been carried out in an attempt to utilize the potential of nanocrystalline metal oxides as substrates for electrochromic devices. A particularly interesting approach has been reported by Fitzmaurice and co-workers [17]. These authors have constructed an electrochromic device based on the combination of... 

Thin film electroluminescent (TFEL) materials are similar to LEDs, in that they are completely soUd-state materials. The difference lies in the application of charge and a higher level of defects. Therefore, TFEL devices require a much higher electrical field than the injection electroluminescence observed in LEDs. However, devices in this category typically possess the possibility of multicolor emission. Mach provides a review similar to that of DenBaars on the application, construction, and properties of various materials in this application.
