產品介紹

The LET-S Series High-Resolution Motorized 2D Material Transfer System is independently developed by our company to meet the demands of specialized experimental setups and high-precision transfer applications. It is designed for precise deterministic transfer of monolayer materials such as graphene, MoS?, and black phosphorus, as well as for the fabrication of multilayer van der Waals heterostructures, enabling visualized manipulation of low-dimensional materials.

The system integrates a high-resolution metallurgical microscope, precision temperature control module, vacuum adsorption system, and high-precision motorized sample and substrate stages. The substrate stage supports large in-plane angular rotation, making it an ideal tool for studying heterostructure characteristics, breaking of spatial inversion symmetry, and the influence of stacking configurations in two-dimensional materials.

Technical Advantages:

Integrated design, easy to operate
High-resolution metallurgical imaging, enabling micron-scale transfer precision
High positioning accuracy with zero-backlash design
Precision temperature control module, adaptable to a wide range of materials

Application Fields:

Twisted-angle superconductivity research
2D material stacking
Van der Waals heterostructure fabrication
Studies on inversion symmetry breaking in heterojunctions
