Title: Innovations of Frederick M Fliegel
Introduction
Frederick M Fliegel is a notable inventor based in Tempe, Arizona, recognized for his contributions to the field of acoustic charge transport devices. With a total of nine patents to his name, Fliegel has made significant advancements in technology that enhance the efficiency and functionality of electronic devices.
Latest Patents
Fliegel's latest patents include a method for reducing heterostructure acoustic charge transport devices, which employs a thin-film overlay of a more strongly piezoelectric material. This innovation allows the device to function as both a delay line and a tapped delay line, or transversal filter, while requiring less total power for the surface acoustic wave (SAW) clock signal. The increased electrical potential per unit total SAW power facilitates better coupling between the total SAW energy and the mobile charge carriers. Additionally, some material systems, such as a GaAs substrate and a ZnO thin-film overlay, may necessitate an intervening thin-film dielectric layer due to chemical, semiconductor device processing, or adhesion incompatibilities.
Another significant patent by Fliegel is an apparatus for reducing heterostructure acoustic charge transport devices, which shares similar functionalities and benefits as his previous patent. This innovation also emphasizes the importance of the thin-film overlay and its impact on device performance.
