Scientists go deep to quantify perovskite properties

Scientists led by Rice University and Los Alamos National Laboratory have discovered electronic properties in quantum-scale devices that are likely to impact the growing field of low-cost perovskite based optoelectronics.

Electron-hole pairs in two-dimensional crystals

When light of specific frequency hits a semiconductor crystal, it is absorbed and produces excitation, a state of higher energy. In solar cells, this energy is converted into electricity. In two-dimensional crystals, which ...

Scientists found excitons in nickel oxide for the first time

Russian scientists from Ural Federal University (UrFU), together with their colleagues from Institute of Metal Physics of the Ural Department of Russian Academy of Sciences, have studied fundamental characteristics of nickel ...

Using the dark side of excitons for quantum computing

To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. As a promising quantum bit, or qubit, it can store information ...

Spontaneous Bose-Einstein condensation of excitons

Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a single ...

The exciting future of light energy

In a world of growing energy needs, and a global imperative to halt carbon emissions, a tiny 'quasiparticle' called an exciton could provide the answer to our problems.

Shedding light on the absorption of light by titanium dioxide

Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is called "anatase". ...
