Exam (elaborations) TEST BANK FOR Introduction to Solid State Physics The vectors xˆ ˆ + + y zˆ and − −xˆ yˆ + zˆ are in the directions of two body diagonals of a cube. If θ is the angle between them, their scalar product gives cos θ = –1/3, whence . 1 cos 1/ 3 90 19 28' 109 28' − θ = = ° + ° = ° 2. The plane (100) is normal to the x axis. It intercepts the a' axis at and the c' axis at ; therefore the indices referred to the primitive axes are (101). Similarly,...

Quantum dots (QD) are an exciting new area of research; they have valuable properties that could further the future of opto-electronic devices. Such properties can be probed by performing photo-luminescence (PL) experiments, which is essentially excitation of the dots by optical means and detecting the photo-luminescence emitted. Using this technique, the temperature and excitation intensity dependence of the PL from four different quantum dots have been investigated.

Quantum dots in cells are used as indicators to track cell lineage. Fluorescence is emitted by the dots upon excitation and is collected using flow cytometry experiments. The fluorescence data obtained gives indication of the quantity of cells within each cell and the amount by which the cells have been diluted due to cell division. Using these data sets, statistical mechanics and information theory will be used to develop mathematical models describing this dilution of dots. Such a mathematical...
