Question

Miller indices of the plane parallel to X and Y axes are
a.(001)

b.(111)

c.(010)

d.(110)

​

Answer 1

Answer:

a is the correct answer

Answer 2

The correct answer is option (d.) (110).

Explanation:

• Miller indices of the plane parallel to X and Y axes are 110.
• Miller indices, group of three numbers that indicates the orientation of a plane or set of parallel planes of atoms in a crystal.
• If a plane is parallel to one of the axes, then it is considered to intersect it at infinity, so the corresponding index is 1/∞, or zero. Also, if a plane has a negative intercept.
• This is denoted in the index with a bar: i.e., a plane with intercepts of -1, ∞, 1/2 would have a Miller index of 1 ¯ 02.
