Twistology could be the study of unexpected changes or developments in stories or situations, from coups d’état to the fatherhood of Darth Vader. In condensed matter physics there is something similar, although the preferred name is twistronics (from twist and electronics). It is understood as the study of how the angle (the twist) between layers […]

Since the discovery of graphene, a wide diversity of atomic-layer-thick, two-dimensional (2D) materials with varied properties have emerged. Of particular interest are those that exhibit semiconducting behaviour, such as hexagonal boron nitride (hBN). hBN is isoelectronic to graphene and has also a honeycomb lattice formed by alternating nitrogen and boron atoms, but in contrast to […]

Over the past several decades researchers have thought how materials and device architectures can efficiently convert solar radiation into electrical power through the photovoltaic effect. Those efforts have led to different methods and processes to produce green energy. In this context, organic photovoltaic (OPV) technology has received considerable attention because it indeed constitutes a new […]

Quantum objects are not abstract entities. On the contrary, they are quite real, As such, individual quantum objects can be detected, manipulated and their characteristics analysed using the appropriate techniques. Take the case of a single molecule adsorbed on a substrate. Scanning Tunneling Microscopy (STM) would reveal electron densities of molecular orbitals, could be used […]

Terahertz (THz) radiation is all around us. For example, this page emits blackbody radiation mainly in the THz region (broadly from 0.3 THz to 30 THz). Because terahertz radiation begins at a wavelength of around one millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter […]

Two-dimensional (2D) materials are extraordinary for two main reasons. One is the set of mechanical properties that makes those materials a versatile playground where multiple modelling objects are possible, from the thinnest membranes with minuscule bending rigidity to very stiff plates, all with very reproducible parameters. The other reason is that both the electronic and […]

“There is something at work in my soul, which I do not understand.” ― Mary Wollstonecraft Shelley (1797-1851), Frankenstein or The Modern Prometheus, 1818 Increasing advances in material’s science have enabled the design and production of materials capable of inducing specific cell behaviors, such as proliferation, migration or differentiation. Consequently, we are now able to […]
