Here, a different and previously under-explored property that is also intrinsic to phase-change materials and devices, namely accumulation, is exploited to demonstrate that nanometer-scale electronic phase-change devices can also provide a powerful form of arithmetic computing. Complicated arithmetic ...
Phase-change materials (PCMs) that can reversibly transit between crystalline and amorphous phases have been widely used for data-storage and other functional devices. As PCMs scale down to nanoscale, the properties and transition procedures can vary, bringing both challenges and opportunities in scalab...
High-speed and large-scale intrinsically stretchable integrated circuits High-density, intrinsically stretchable transistors with high driving ability and integrated circuits with high operation speed and large-scale integration were enabled by a combination of innovations in materials, fabrication process desig...
A universal mechanical exfoliation method of creating freestanding membranes of complex-oxide materials with different crystal structures and orientations and stacking them to produce a range of artificial heterostructures with hybridized physical properties is described.

Nanotechnology can be defined as the design, synthesis, and application of materials and devices whose size and shape have been engineered at the nanoscale. It exploits unique chemical, physical, electrical, and mechanical properties that emerge when matter is structured at the nanoscale. View ...
When independent layers of electrons and holes are in close proximity to each other, their Coulomb interaction allows them to pair into neutral bosons and form an insulating state. This phenomenon is reported in a heterostructure of 2D materials. Zuocheng Zhang , Emma C. Regan & Feng Wang Ar...
