Symmetry breaking in 2D layered materials plays a significant role in their macroscopic
electrical, optical, magnetic and topological properties, including, but not limited to, spin …

The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

The photocurrent generation in photovoltaics relies essentially on the interface of pn junction
or Schottky barrier with the photoelectric efficiency constrained by the Shockley-Queisser …

In noncentrosymmetric materials, the responses (for example, electrical and optical)
generally depend on the direction of the external stimuli, called nonreciprocal phenomena …

For many materials, a precise knowledge of their dispersion spectra is insufficient to predict
their ordered phases and physical responses. Instead, these materials are classified by the …

We study the low-frequency properties of the bulk photovoltaic effect in topological
semimetals. The bulk photovoltaic effect is a nonlinear optical effect that generates dc …

The discovery of ferromagnetic order in monolayer two-dimensional (2D) crystals has
opened a new venue in the field of 2D materials. Two-dimensional magnets are not only …

Cation mixing in two-dimensional (2D) hybrid organic–inorganic perovskite (HOIP)
structures represents an important degree of freedom for modifying organic templating …

Rectified electric current induced by irradiating light, a so-called photocurrent, is an
established phenomenon in optoelectronic physics. In this paper, we present a …

Bulk photovoltaic effect (BPVE), a second-order nonlinear optical effect governed by the
quantum geometric properties of materials, offers a promising approach to overcome the …
