To calculate the surface energy of the 100 plane of niobium, you'll need to know the crystal structure of niobium and its surface energy in a particular unit.

Step 1: Determine the crystal structure of niobium
Niobium has a body-centered cubic (BCC) crystal structure. In the BCC structure, each atom has eight nearest neighbor atoms.

Step 2: Find the equilibrium lattice constant
Obtain the equilibrium lattice constant (a) of niobium. This value can be found in materials databases or scientific literature.

Step 3: Calculate the surface energy
The surface energy (γ) can be calculated using the formula:

γ = E_surf / A

where E_surf is the energy of the surface and A is the area of the surface. The energy of the surface can be found using molecular dynamics simulations or density functional theory (DFT) calculations.

Step 4: Determine the area of the 100 plane
In the BCC structure, the area of the 100 plane can be calculated as:

A = a^2

where a is the equilibrium lattice constant.

Step 5: Substitute the values and calculate
Substitute the known values into the formula to calculate the surface energy:

γ = E_surf / A

Remember to use consistent units for all the values involved in the calculation.

It is worth noting that calculating surface energy can be a complex process and often requires advanced computational techniques. If you don't have access to the necessary software or expertise, it might be easier to consult literature or research papers to find the surface energy values for the 100 plane of niobium.
