Detailed transmission electron microscopy imaging of the dynamics of domain walls in twisted van der Waals ferroelectrics is obtained, capturing the transition to a hysteretic response. A central ...

Isolated CdSe nanoparticles, also known as quantum dots (QDs), were prepared in our laboratory following established wet-chemistry procedures 2,8. The particle radius varied from 1.4 to 2.4 nm, with a ...

Polarizability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now ...
