An alternative reconstruction composed by CeO4 pyramids exposing Ce atoms has also been recently suggested. This termination is slightly more stable (0.003 eV A~(-2)) than the oxygen terminated and would account for the cerium-terminated regions.M. Capdevila-Cortada...
In crystals, the cubic temperature dependence of phonons at low temperature reflects the temperature dependence of the volume of the Debye sphere when the mean-free-path is saturated to a constant value. In glasses, the asymptotic low-temperature dependence of thermal conductivity is close to ...
In a silicon lattice, all silicon atoms bond perfectly to four neighbors, leaving no free electrons to conduct electric current. This makes a silicon crystal an insulator rather than a conductor. Metals tend to be good conductors of electricity because they usually have "free electrons" th...

The packing fraction measures the ratio of the volume of atoms in a cell compared to the total volume of a cell. Since the diamond lattice is face-centered cubic, the equation can easily be solved by making substitutions. Calculate the packing fraction =

lattice parameter or cell side length. The zinc-blende unit cell can be visualized as two overlapping, face-centered unit cells slightly displaced with respect to each other. The atoms in the zinc-blende structure pack tightly together, so you can relate the lattice parameter to the size of ...
Inside an iron bar, there are billions of iron atoms held together in a rigid structure called a crystal lattice. It's a bit like a climbing frame with atoms at the joints. Although the atoms are pretty much fixed in the same place, they are constantly jiggling about. Each atom has a...
The simplest answer is to use abridge. Sounds easy, perhaps, but which type of bridge do you use? Why are there so many different types and how do they all work? Let's take a closer look and find out more! Photo: One of the world's greatest bridges. Over 150 years after it was...
