Modeling Bound States In The Continuum For Multiple Electrons In A Quantum Dot Pair, Thomas Ian Tuegel
Modeling Bound States In The Continuum For Multiple Electrons In A Quantum Dot Pair, Thomas Ian Tuegel
Undergraduate Honors Thesis Collection
The bound eigenstates of an electron inside a pair of quantum dots embedded on an infinite quantum wire are examined using the method of particular solutions. The eigenstates of a two-electron system in the same structure are examined perturbatively using wavefunction expansions for the one-electron eigenstates. The stability of the two-electron eigenstates is evaluated and compared with other theoretical results. It is found that stable bound states in the continuum exist for two electrons confined to this geometry.
Determination Of Energy Level Excitation States Of Time Dependent Optogalvanic Signals In A Discharge Plasma, Michael Christopher Blosser
Determination Of Energy Level Excitation States Of Time Dependent Optogalvanic Signals In A Discharge Plasma, Michael Christopher Blosser
Undergraduate Honors Thesis Collection
When tuning a laser between two excited energy levels of the atoms in a discharge plasma, the discharge current will temporarily be disturbed. This disturbance or change in current is the optogalvanic effect (OGE). The fundamental goal of this project is to determine the exponential rates in the time-dependent OGE signals. These rates are related to the collision rates for the atoms in the plasma. The OGE data will be experimentally recorded, fitted, and analyzed to extract the exponential rates related to the energy levels of the atom in gas in the discharge lamp.
