In the typical materials that we encounter every day-and even in state-of-the-art chips in computers-electrons move around in three dimensions (3D). However, scientists can force electrons to move around in two dimensions (2D) by creating ultra-thin materials like graphene.
For decades, scientists have been probing the potential of two-dimensional materials to transform our world. 2D materials are only a single layer of atoms thick. Within them, subatomic particles like electrons can only move in two dimensions.
When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found in other materials.
A large-scale (4-inch), highly uniform, and defect-free plasma etching technology, which will likely become the foundation of the industrial supply of molybdenum disulfide (MoS2), a next-generation two-dimensional (2D) semiconductor, has been developed.
Since the revelation of the 2D variant of graphite (dubbed graphene) nearly two decades ago, the fascination with 2D materials and their distinctive physical properties has surged.
Digital Surf today announced the release of the tenth major version of the company’s renowned Mountains® software analysis platform for surface metrology & microscopy, trusted by 50+ leading instrument manufacturers and 22,000+ users.
Since its discovery more than 100 years ago, ferroelectric materials still garner much attention in research due to their wide-ranging applications, from data storage to renewable energy systems.
The group led by Professor Naoya Shibata of the University of Tokyo, in collaboration with Sony Group Corporation, succeeded in directly observing a two-dimensional electron gas that accumulated at the semiconductor interface.
A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials - like a tailor altering a suit - could be just the tool for designing the technology of a sustainable energy future.
A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
