A simple structural tweak has dramatically enhanced the colour clarity and stability of heavy metal-free blue quantum dots.
Argonne scientists have unveiled new methods for controlling material properties. The breakthrough enables researchers to ...
Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a ...
Argonne researchers have shown that they can use light to temporarily alter the crystal symmetry within lead sulfide quantum dots. This process reduces the off-centering of lead atoms and affects the ...
In their case, the dots are not created by dabbing a paintbrush ... investigated special materials with a triangular crystal lattice (moiré materials made of transition metal dichalcogenides).
What’s new about this is that the dots are precisely arranged to simulate ... model describes a single electron moving along a one-dimensional lattice with staggered tunnel couplings.
One of the tricks that researchers have used for a while now consists in reducing the motional energy of the electrons by artificially creating a crystal lattice with a large lattice constant ...
A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.
