摘要：

Direct integration of ferroelectrics with semiconductors is critical to lower the cost and simplify the production procedures for data storage/processing components and miniature sensor/actuator development. By optimizing magnetron sputtering parameters, highly <001> preferential growth of BaTiO3 thin films with reproducible ferroelectric responses have been achieved on Si(001) substrates. The thin film ferroelectric characteristics were systematically studied by piezoresponse force microscopy, and a piezoelectric coefficient d(33) of 24pm/V has been measured. It is found that the scanning tip sidewall angle and cantilever tilt affect the contour and size of polarized area.
