Suppose you have a very small sample of the orthorhombic crystal (orthorhombic, lattice constants 5.3 Å, 5.4 Å and 5.5 Å). The crystal is 53 nm x 54nm x 55 nm oriented along the respective axis. [2] Show for this crystal, there are one million atoms. [2] If the crystal has dimensions 53nmx54nmx55nm, calculate the smallest and largest phonon wave vectors for this crystal (state answer in mks). [2] What exactly is a phonon and why do we use them?

Three identical blocks of metal are initially at temperatures T(A = 400 K, TIB-500 K and T-600 K respectively. Each block has a mass of 5 kg, and its stable equilibrium states can be described by the relationss TI where E is energy, S is entropy, m is the mass, T is temperature, and C = 2 kJ/(kg·K) is the specific heat capacity. The local environmental temperature is TR To 298 K. Moreover, the same parametric relations hold for the...

EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...
