A fundamental goal of physics is to explain the broadest range of phenomena with the fewest underlying principles. Remarkably ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

Because of this, the second layer will only cover half of the holes in the first layer. pattern shown here. Since I realize that it is difficult to pin point the actual unit cell from the lattice, let ...

Graphene — a single layer of carbon atoms arranged in a honeycomb lattice — is already attracting interest for its various applications in electronics and optoelectronics, including its use as ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

Copper and zinc atoms are different sizes. This distorts the regular lattice structure in brass, so layers of atoms cannot slide over each other so easily. This makes brass stronger than copper or ...
