FAQ

What is the Lattice Constant a?
The Lattice Constant a refers to the physical dimension of unit cells in a crystal lattice along x-axis. Lattice Constant a is usually measured using the Angstrom for Length. Note that the value of Lattice Constant a is always negative.
Can the Lattice Constant a be negative?
Yes, the Lattice Constant a, measured in Length can be negative.
What unit is used to measure Lattice Constant a?
Lattice Constant a is usually measured using the Angstrom[A] for Length. Meter[A], Millimeter[A], Kilometer[A] are the few other units in which Lattice Constant a can be measured.
