Growth of ZnSiN2

Alexander Grutter with Kathy KashGrowth of ZnSiN2Zinc Silicon Nitride (ZnSiN2 ) is an extremely wide band-gap semiconductor which has never been grown before. With this senior project I will attempt to grow ZnSiN2 by first designing and building a crystal growth system, and then by finding a “recipe” for...

Quantum Dots in a Strong Magnetic Field – Charging Energy of a Quantum Dot in the Thomas-Fermi Approximation

Alex Harvey with Harsh MathurQuantum Dots in a Strong Magnetic Field - Charging Energy of a Quantum Dot in the Thomas-Fermi ApproximationQuantum dots are nanometer scale semiconductor structures.  Their small size leads to unique behavior different from that of macroscopic semiconductors.  Our objective is to generalize the Thomas-Fermi method...

Modeling Shimmy on Bicycles

Jennifer Kotzin with Gary ChottinerModeling Shimmy on BicyclesIn bicycling and motorcycling, there are times in which the headtube and steerer begin to oscillate, often strongly enough to throw the rider or force a crash. Those who have experienced it have nicknamed this effect the ‘Death Wobble'. This project will...

Cosmic Strings and Magnetic Field

Samuel Rivier with Harsh MathurCosmic Strings and Magnetic FieldCosmic strings are linear structures that are hypothesized to have formed in the early universe and to have had considerable influence on the evolution of the universe. Cosmic strings interact with astrophysical objects via their graviational field and electromagnetic interactions. Relatively...
