0/4 pts Question 4 The following figure depicts a unit cell for a body-centered cubic lattice (which is one of the 14 lattice types that are possible in 3D) Note there are lattice points at each cube corner and one lattice point exactly in the center of the cube Which option below represents the correct fractional lattice vector triplets (fractional unit vector components) associated with the location of each point in this unit cell? Assume the origin is associated with point #1. Also recall the standard axes settings for crystallography (x-out of viewing plane whereas y-& z-are in the viewing plane). 4 6 3 2 9 8 #1 0.0.0 #1 0,1,0 #2 #3 1,1,1 #4 0,0,1 #5 0,1,1 #6 1,0,1 #7 1,0,0 #8 1,1,0 #9 0,1,0 #1 0.0.0 #2 #3 1,1,1 #4 0,0,1 #5 0,1,1 #61,0,1 #7 1,0,0 #8 1,1,0 #90,1,0 #11.0.0 #2 112, 112, 1/2 #3 1,1,1 #40.0.1 1/2,1/2, 112 #3 1,1,1 #4 0,1,1 #50,0,1 #61.0.1 #7 1,0,0 #8 1,1,0 #9 0,1,0 1/2, 112, 1/2 112, 112, 1/2 #2 #61.0.1 #7 0, 0, 0 #81.1.0 #9 0, 0, 0

Explanation / Answer

feel free to drop comment if you have any doubt.

Point 1 - its 0 0 0 . ( C & D are correct)

Point 2 - its 1/2 1/2 1/2 ( C & D are correct )

Point 3 - its 1 1 1 (C & D are correct )

Point 4 - its 0 1 1 ( only D option is correct )

So here in this question Answer must be OPTION ( D ).

i am providing the direction for rest of points too but we need to check for only 4 points to get the correct answer.

Point 5 - its 0 0 1 ( Optioin D )

Point 6 - its 1 0 1 (Option D )

Point 7 - its 1 0 0 ( Option D )

Point 8 - its 1 1 0 ( Option D )

Point 9 - its 0 1 0 ( Option D )
