Fabrication Of Two-Dimensional Nanostructures On Glass Using Nanosphere Lithography, Elmer Jim Wang

Wayne State University Theses

It is desired to have artificial optical materials with controllable optical properties. Optical glass is the most common optical material for various applications. This research will attempt to create a thin layer on the substrate with controllable optical properties. The thin layer is a composite material with nanoscale features and controllable refractive index. Two-dimensional (2D) nanostructures will be created on the surface of optical glass using nanosphere lithography. In comparison with conventional techniques, this approach is more efficient and cost-effective for the creation of large areas of thin surface layers as an artificial material. A uniform monolayer of nanospheres will …

An Apparatus For Verification Of Absolute Calibration Of Quantum Effiency For Charge-Coupled Devices, Rebecca Ann Coles

Wayne State University Theses

The LBNL Microsystems Laboratory produces backside illuminated, high resistivity, p-channel, charge-coupled devices (CCDs). A system was developed to test the quantum efficiency (QE) of the CCDs; the percentage of electrons that are emitted from the CCD surface per amount of light that it's exposed to.

The QE system was designed and constructed to test CCDs of a much smaller size then what is currently produced. To continue testing, I redesigned the QE apparatus to make room for the new, larger size, CCDs while still preserving measurement accuracy. I removed the photodiode that formally sat alongside the CCD in the Dewar, …
