| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | RF signal can be converted to DC signal using an antenna and diode (rectenna). When distance of wireless transfer is long, RF-DC conversion efficiency is inefficient because a weak RF signal cannot exceed the threshold voltage of the diodes in the rectenna. This study proposes resonator type piezoelectric transformer based on c-axis zig-zag ScAlN films. Solidly mounted resonator (SMR) type transformer using an acoustic Bragg reflector enables a wider bandwidth operation than previously reported film/substrate type transformer.. As a result, zig-zag multilayers where c-axis oriented 180° symmetrically on the acoustic Bragg reflector was fabricated by oblique RF magnetron sputtering. Voltage gain of 2.7 and the fractional bandwidth of 3.2% which was 46 times wider than that of film/substrate type transformer were observed. | |
