Piezoelectric semiconductor thin film polarization experimental device

Abstract

The invention discloses a piezoelectric semiconductor thin film polarization experimental device. The piezoelectric semiconductor thin film polarization experimental device comprises a cabinet body, the top part of which is provided with a left guiding column and a right guiding column along a vertical direction. The top part of the cabinet body between the left guiding column and the right guiding column is fixedly provided with a heating plate and a first motor. The rotating shaft of the first motor is vertically upwardly provided with external screws, and a quartz glass tube is disposed on the heating plate. A carrying plate is disposed on the quartz glass tube, and the rotating shaft of the first motor passes through the carrying plate, and is in a threaded connection with the carrying plate. The left end and the right end of the carrying plate are slidably connected with the left guiding column and the right guiding column. The bottom part of the carrying plate is fixedly provided with a polarization clamp. The safe and easy-to-operate piezoelectric semiconductor thin film polarization experimental device capable of realizing temperature variation is realized.

Problems solved by technology

However, there is currently no polarization device for piezoelectric semiconductor thin film materials, which cannot meet the production and research needs of piezoelectric semiconductor thin films

Moreover, the current device has a single function, generally exposed to the air and polarized, with poor safety, no integrated heating system, and a heating furnace is often used as a supporting device, which is difficult to apply to the requirements of laboratories and enterprise R&D pilot tests.
