Masses coupled through springs is a model for the behavior of atoms in a crystal. Consider a one-dimensional crystal, what if we have a crystal made of two kinds of atoms with different masses? Consider a one-dimensional lattice made up of alternating large and small masses, M and m, respectively. Assume periodic boundary conditions. (a) Calculate the normal modes of this lattice (you should find two normal modes). (b) Describe the relative motion of the two types of masses for each mode.

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.

A certain crystal is cut so that the rows of atoms on its surface are separated by a distance of 0.352 nm. A beam of electrons is accelerated through a potential difference of 175 V and is incident normally on the surface. If all possible diffraction orders could be observed, at what angles (relative to the incident beam) would the diffracted beams be found? (The surface acts as a diffraction grating where maxima occur when d sin? = n?, n...

A mass spectrometer is designed to calculate masses of atoms. A source produces positive ions of mass m and charge q. The ions move with a velocity v to the right, pass through a narrow slit S1 and enter a region between two charged plates. In this region they experience both an electric and a magnetic field. The electric field E is caused by the 2 charged plates; the upper plate is (-) charged and the lower plate is (+)...

In the Einstein model, atoms are treated as independent oscillators. The Debye model, on the other hand, treats atoms as coupled oscillators vibrating collectively, but the collective modes are regarded as independent. Explain the meaning of this independence, and contrast it with that in the Einstein model
