Laser diode (LD) chips do not suffer the “efficiency droop” effects under high-density current driving to the extent that LED chips do, and are therefore considered a promising next-generation solid…

Zero-index metamaterials (photonic materials and artificial media with a near-zero refractive index in different parts of the electromagnetic spectrum) make possible novel forms of light-matter interactions where light behaves in…

Spin-based electronics (spintronics) aims at extending electronic functionalities, which rely on the electron charge as information carrier, by the spin of the electron. Spintronics has large application potential in information…

In the past decade, thermoelectric (TE) materials science and technology has received unprecedented attention due to potentially disruptive solutions in critically important areas associated with global energy use and environmental…

The investigation of unique electrical, thermal and optical properties of graphene and two-dimensional van der Waals materials resulted in numerous exciting developments in fundamental science and practical applications. Now, a…

The unique properties of wide- and ultrawide-bandgap semiconductors make them ideal for the next generation of power electronic devices and RF amplifiers. Their high critical electric field, in combination with…

Conventional optical microscopy techniques, even in super-resolution, are limited in spectroscopic image content, as desired for the study of functional molecular and quantum materials. In recent years, a range of…
