CCL: RUTILE 110 SURFACE

> Saurabh:

> You need to look in a book on crystallography. Rutile forms in tetragonal prisms. The plane you want (1,1,0) is the cleavage plane.

> Anyway, these three numbers are the Miller indices. The plane you are looking for is one full lattice spacing in the a-direction, one full lattice spacing in the b-direction, an no displacement in the c-direction. If you have access to an elementary graphics program, you can input the coordinates you supplied, the lattice constants you supplied, and the program will draw the unit cell. From this you can determine the cleavage plane.

> Dear CCL Subscribers,

> I am trying to make 110 rutile surface form the 1x1 lattice coordinates given below. I could replicate the surface using moe software. But I am not sure which side of the surface is 110. Any information or tutorial helpful to solve this problem would be of much help for me.
