With the rapid development of integrated circuits, there is an increasing need to boost transistor density. In addition to shrinking the device size to the atomic scale, vertically stacked interlayer interconnection technology is also an effective solution. However, realizing large‐scale vertically interconnected complementary field‐effect transistors (CFETs) has never been easy. Currently‐used semiconductor...
Two‐dimensional (2D) coplanar heterostructure enables high‐performance optoelectronic devices, such as p–n heterojunctions. However, realizing site‐controllable and shape‐specific 2D coplanar heterojunctions composed of two semiconductors with the same crystal orientation still requires the development of new growth methods. Here, a route to fabricate MoS2–MoTe2 coplanar heterojunctions with the same...
The change of 3D spatial distribution of magnetic permeability can lead to the generation of introduced electrical signals. However, present studies can only achieve rough regulation by simple shape deformation of magnetic elastomers such as compression, bending, or stretching. Accurate control of the 3D spatial distribution of magnetic permeability is still an open question. In this study, an on‐demand...
The detection of biomolecules at the single molecule level has important applications in the fields of biosensing and biomedical diagnosis. The solid‐state nanopore (SS nanopore) is a sensitive tool for detecting single molecules because of its unique label‐free and low sample consumption properties. SS nanopore translocation of small biomolecules is typically driven by an electronic field force and...
