## How do you find the Miller indices of a plane?

Here is the 3-step process to find the miller indices for planes.

- Find the point where the plane intersects each axis. If the plane never intersects an axis because it is parallel to that axis, the intersection point is ∞.
- Take the inverse of each intersection point.
- Put those 3 values in the proper (hkl) format.

## What is Miller indices family of planes?

The Miller indices (hkl) usually refer to the plane that is nearest to the origin without passing through it. You must always shift the origin or move the plane parallel, otherwise a Miller index integer is 1/0! Sometimes (hkl) will be used to refer to any other plane in the family, or to the family taken together.

**What will be the Miller indices of the plane ABC?**

The Miller indices of the planes ABC’, ABC, ABC” , AA”BB” are (112), (111), (221), (110), respectively.

**How many atoms are in a FCC 111 plane?**

2 atoms

For the (111) plane there are N111 = 3 × (1/6) + 3 × (1/2) = 2 atoms within the unit cell. The (110) plane has the highest atomic density and hence is best for p-channel MOSFET performance.

### What is the Miller indices of the plane 2a B C?

We have the intercepts as 2a, 2b, and 3c. Hence, the miller indices for the given plane is calculated as 332.

### What will be the Miller indices of a plane having intercepts 3 co ordinate axis 3a 2b 2c?

Hence, the miller indices for the given plane is 332.

**What is the Miller index notation for the direction normal to the plane?**

These are the MILLER INDICES of the plane. The NORMAL to the plane is the [4,3,2] direction, which is normally written just [432]. (A negative number is indicated by a bar over the top of the number.)

**How many 111 planes are in the FCC?**

4 octahedral planes

FCC slip occurs on close-packed planes in close-packed directions. There are 4 octahedral planes, (111), (111), (111), and (111), six <110> directions, each one common to two octahedral planes, giving 12 slip systems.

#### What is a 100 plane?

The Beriev A-100 is a Russian-built airborne early warning and control (AEW&C) aircraft based on the Il-76MD-90A transport aircraft. This aircraft is developed to replace the Beriev A-50 in Russian Air Force service.
