A new paradigm to break the electromagnetic reciprocity in 3D bulk metamaterials
Transistors based on semiconductor materials are widely used electronic components with many remarkable properties. For instance, they have a nonreciprocal electrical response, which means that they can isolate two parts of a circuit in such a way that one of the...
Study unveils a Moiré nematic phase in twisted double bilayer graphene
Moiré superlattices are systems in which two sheets of a material are placed on top of each other with a small angle misalignment, resulting in a characteristic pattern known as the Moiré pattern. In recent years, many physicists and material scientists have been...
Study shows that monolayer tungsten ditelluride is an excitonic insulator
Tungsten ditelluride (WTe2) is a transition metal dichalcogenide with numerous advantageous properties and characteristics, which makes it an ideal material for a wide range of electronic applications. Past studies have established that 2D WTe2 crystals arranged...
Study reports the ferroelectric switching of spin-to-charge conversion in germanium telluride
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, the development of these devices has been...
A strategy to control the spin polarization of electrons using helium
Spintronics, also known as spin electronics, is a research field that explores how the intrinsic spin of electrons and its magnetic moment can be exploited by devices. Spintronic devices are promising for a wide range of applications, particularly for efficiently...
The first unequivocal experimental evidence of a superfluid state in 2D 4He films
Over the past few decades, some physicists worldwide have been trying to use the second layer of 4He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid phases of matter. Some teams have collected torsional oscillator...
