Ultra high quality two-dimensional material transfer system

---

The system consists of a rapid injection chamber, a cleavage chamber, a low-temperature sample holder, a cleavage sample holder, and an optical microscope. Easy to operate, with the help of a robotic arm, two-dimensional material cleavage and transfer can be achieved; The flatness of the cleavage plane at the atomic level.

1. Optical microscope: imported optical lenses with 10x, 20x, 50X zoom; Imported CCD camera; Electric focusing; Coaxial light illumination.

2. Cleave cavity: ultra-high vacuum cavity made of 55316 stainless steel material; High strength aluminum alloy bracket, large rollers, easy to move; Equipped with heating treatment and temperature control functions; Ultra high vacuum environment cleavage, with a vacuum degree better than 5X10-10mbar; Configure liquid nitrogen refrigeration with a minimum temperature of less than 120K.

3. Low temperature sample holder: manual lifting and rotation; Temperature range: 100K-300K; Simultaneously park up to 42 sample trays.

Targeting two-dimensional materials with high vacuum requirements such as BISCCO, iron-based, copper based, and kagome for high-temperature and low-temperature superconductivity
