1. Compare the energy of the crystal containing an edge dislocation with that of a crystal without an edge dislocation. Which has a higher energy and why?? Determine how much higher the energy is in terms of shear modulus and burger vector

Expert Solution

I have given a rough comparison between these two energies mathematically.The final answer may not be the exact one so I have written some literature .please read it.If you have any doubt then comment on it.

Dislocation in metals Describe edge dislocation motion in metals from an atomic perspective. Be sure to clearly illustrate the sequence in which bonds are broken and reformed. Also from an atomic perspective, describe how macroscopic plastic deformation occurs by the motion of dislocations in response to an applied stress. Again, use words and visuals to explain.

The energy of formtion of a vacancy in the copper crystal is about 1 eV. Calculate the concentration of vacancies at room temperature (300K) and just below the melting temperature, 1084oC. The atomic mass of Cu is Mat = 63.54g*mol-1 and the density at 293 K is 8.96cm-3. Neglect the change in the density which is small.

At what energy does the K-edge occur?

The surface energy of a single crystal depends on crystallographic orientation. Does this surface energy increase or decrease with an increase in planar density? Why? (Hint: Read “External Surface” part in S.4.6: Surface energy is proportional to the number of unsatisfied bonds of surface atoms) please clear hand writing, also plesae don't give me the book answer. Thank you.

Cohesive energy of a crystal is the energetic cost that holds all atoms together in a crystal. It can be determined both experimentally and theoretically. Explain, based on your knowledge on the quantum mechanical nature of non–covalent interactions, why the following statement is incorrect: Because silicon crystal are bonded together by strong covalent bonds between silicon atoms, non– covalent interactions, in particular, dispersion interactions, play NO role in determining the cohesive energy in silicon crystals.
