With the aim of preparing photoinduced electron transfer devices or simply to be used as fluorescent reporter groups, the synthesis and utility of pyrene-L-alanine have been reported on several occasions. Regarding the development of charge-transfer devices, it was shown that intramolecular electron transfer occurred in 310- and a-helical peptidic systems, such as 182 and 185, between a pyrene and a dimethylaminophenyl chromophore (Scheme 51).[95 101] The rates depend on the relative orientation of the chromophoric side chains and on the framework conformation. Therefore, the preparation of tailor-made charge-transfer devices with tunable properties can be envisaged. 

A uniphase, buried-channel charge transfer device is disclosed in US-A-4229752 wherein a portion of each cell includes an inversion layer, or "virtual electrode" at the semiconductor surface, shielding that region from any gate-induced change in potential.

A charge transfer device formed in HgCdTe where the distances between transfer electrodes and a substrate are equal is disclosed in JP-A-57062563. 

A charge transfer device infrared sensor matrix 22 comprises CCD elements 24 arranged in rows and columns. Each element 24 is formed on a mercury cadmium telluride substrate. The electrodes of the CCD elements are connected by metallized bus lines 44 to a four phase... 

Thereafter, HgCdTe detector regions 13 are grown on the silicon substrate and individual detector elements are connected to the charge transfer device.

CCDs and CIDs are appearing in ever-increasing numbers in modern spectroscopic instruments. In spectroscopic applications, charge transfer devices are used in conjunction with multichannel instruments, as discussed in Section 26B-3. In addition to spectroscopic applications, charge transfer devices find widespread applications in solid-state television cameras and microscopy.
