This assignment must be completed individually and turned in to your TA at the beginning of lab. You will not be allowed to begin the lab until you have completed this assignment.

  • List the existing crystal systems (unit cell types):
  • Which of these unit cells will we study in this laboratory exercise?
  • Which are the three subclasses of this type of unit cell?
  • Define coordination number:
  • What is the volume of a sphere? Of a cube?

Report: solid state and superconductors

Part I Demonstration and Unit cell theory

A. TA Demo of the superconductor

Describe and explain your observations (What happens with the magnet? Briefly describe the Meissner effect?)

 

 

B. The unit cell 1. A cube (see below) has _______ corners, _______ edges&_______ faces.

2. Structure A below shows how a unit cell may be drawn where one choice of unit cell is shown in bold lines. In Structures B, C and D below, draw the outline(s) of the simplest 2-D unit cells (two-dimensional repeating patterns depicted by a parallelogram that encloses a portion of the structure).

If the unit cell is moved in the X,Y-plane in directions parallel to its sides and in distance increments equal to the length of its sides, it has the property of duplicating the original structural pattern of circles as well as spaces between circles. Can a structure have more than one type of unit cell? ________

 

Structure A Structure B Structure C Structure D

3. If the circle segments enclosed inside each of the bold-faced parallelograms shown below were cut out and taped together, how many whole circles could be constructed for each one of the patterns:

     

4. Shown below is a 3-D unit cell for a structure of packed spheres. The center of each of 8 spheres is at a corner of the cube, and the part of each that lies in the interior of the cube is shown. If all of the sphere segments enclosed inside the unit cell could be glued together, how many whole spheres could be constructed?

 

number of whole spheres: ________

5. For each of the figures shown below, determine the number of corners and faces. Identify and name each as one of the regular geometric solids.

AB

  A B
Number of corners    
Number of faces    
Name of the shape of this object    

 

 

 

Part II Experimental

  • Cubic Cells

A. simple cubic unit cells or primitive cubic unit cells (p)

a. How would you designate the simple cube stacking - aa, ab, abc, or some other?
