Abstract
A van der Waals stacked Josephson junction structure and a method for fabricating the same are provided. The van der Waals stacked Josephson junction structure according to an embodiment of the present disclosure includes a substrate, a first layer of a van der Waals material separable into layers and positioned on the substrate, and a second layer of the van der Waals material positioned on the first layer, in which the first layer and the second layer are twisted at a predetermined angle with each other, and a Josephson junction is formed between the first layer and the second layer.
Claims11
A van der Waals stacked Josephson junction structure comprising:
- a substrate;
- a first layer of a van der Waals material separable into layers and positioned on the substrate;
- and
- a second layer of the van der Waals material positioned on the first layer, wherein
- the first layer and the second layer are twisted at a predetermined angle with each other, and
- a Josephson junction is formed between the first layer and the second layer.
A method for fabricating a van der Waals stacked Josephson junction structure, comprising:
- disposing a Van der Waals material separable into layers on a substrate;
- separating the van der Waals material into a first layer remaining on the substrate and a second layer separated from the first layer using a separation tool;
- twisting the first layer and the second layer at a predetermined angle with each other, and
- stacking the second layer on the first layer in a state of being twisted at the predetermined angle.
