dc.descriptionFabrication of the bimorph lithium niobate cantilevers involves a micro machining of a z-cut wafer to create a multidomain structure. After etching, the bimorph ferroelectric cantilevers are fabricated at the locations near interdomain walls. Cantilever vibrations are excited by rf voltage due to piezoelectric effect in a ferroelectric chip, and optical detection is employed to pickup the vibrations. The self-assembling layers of two different Silanes are chemically deposited on the micro cantilevers. The layers are detected independently by two methods including a low frequency shift of cantilever natural vibrations, and Raman spectral lines from the Silane layers. Possible applications include smart biosensors in a real time domain.
