In semiconductor heterostructures, reconfiguring the band-edge states and modulating their interplay with charge carriers in a continuous manner have been long-standing challenges.
Telecommunications have reshaped many aspects of our lives over the past few decades by providing incredibly convenient ways to share and access information. One of the most important enablers for this transformation has ...
Quantum dots are clusters of some 1,000 atoms which act as one large "super-atom." It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, ...
A UNSW paper published recently in Nature Reviews Materials presents an exciting overview of the emerging field of 2D ferroelectric materials with layered van der Waals crystal structures, a novel class of low-dimensional ...
High-performance photodetectors with great detection capability have been widely deployed in our daily life, such as driverless technology, intraoperative navigated surgery, face recognition, anti-counterfeiting, and so on. ...
An ultrathin dielectric meta-lens has been created that improves focusing capabilities but can also be scaled down to a tiny size for integration with photonics equipment.
Transition metal dichalcogenides (TMDCs) are a class of materials with physical properties that make them ideally suited for use in flexible optoelectronic applications, such as light detectors, light-emitting diodes and ...
In thin, two-dimensional semiconductors, electrons move, spin and synchronize in unusual ways. For researchers, understanding the way these electrons carry out their intricate dances—and learning to manipulate their choreography—not ...
Developing low-cost and stable metal electrodes is crucial for mass production of perovskite solar cells (PSCs). As an earth-abundant element, Cu becomes an alternative candidate to replace noble metal electrodes such as ...
Computers that can make use of the "spooky" properties of quantum mechanics to solve problems faster than current technology may sound alluring, but first they must overcome a massive disadvantage. Scientists from Japan may ...
