MSE Project #1: Materials Science in Three Dimensions
Faculty Mentor: Ashwin J. Shahani, [email protected]
Prerequisites:
-
Familiarity with MATLAB, Python, or an equivalent computing environment
Project Description:
Real materials live in three dimensions. Our ability to probe a material in three dimensions (without destroying it) will lend itself to new insights on the evolution of new technological materials during processing and service. In this project, the SURE student will develop new computational workflows to excavate quantitative information from three dimensional datasets collected via x-ray imaging techniques. Some of these workflows will rely on machine learning in order to excavate information from the high dimensional data as efficiently as possible.
Research Mode: Hybrid (or remote if desired)
MSE Project #2: MACRO: Silsesquioxanes as Components in Hybrid Photovoltaics
Faculty Mentor: Richard M. Laine, [email protected]
Prerequisites:
- none
Project Description:
Silsesquioxanes are polyhedral structures that consist of an inner silica cage which are appended functional organic groups. Selected structures are shown below. The iodo T8 compound provides access to a wide variety of materials and especially to polymers (not shown). All of these materials seem to show 3-D conjugation in the excited state even in polymer chains…suggesting semiconducting behavior rather than the behavior expected for an insulating cage. The project will involve the synthesis and/or characterization of the properties of these materials.
Research Mode: In Lab
MSE Project #3: All Solid-State Batteries
Faculty Mentor: Richard M. Laine, [email protected]
Prerequisites:

MSE Project #4: Nanostructural Characterization of Bioinspired Polymer Proteins
Faculty Mentor: Abdon Pena-Francesch, [email protected]
Prerequisites:
-
Prior experience in a chemistry lab
Project Description:
Proteins are described by their amino acid sequence, which regulates how they fold and self-assemble into well-defined nanostructures. In structural proteins (with a primarily mechanical function such as spider silk or collagen), these self-assembled nanostructures provide control over the mechanical properties (modulus, elasticity, strength, etc.). In this project, the student will characterize structural proteins from cephalopods with infrared spectroscopy, microscopy, and rheology to develop sequence-structure-property relationships. The student will support the lab in the development of protein-based underwater adhesives.
Research Mode: In Lab

Activities may include thin film deposition, battery cell fabrication, chemical synthesis, electrochemical measurements, building circuits, and data analysis. The student must be willing to follow laboratory safety protocols and help maintain a strong laboratory safety culture.

MSE Project #13: Gallium Nanoparticle Plasmonics
Faculty Mentor: Rachel Goldman, [email protected]
Prerequisites:
- A strong interest in experimental science and/or engineering is required.
- Completion of Introductory Chemistry and Physics Labs is preferred but not required.
Project Description:
Metal nanoparticle arrays often exhibit collective electron oscillations (plasmon resonances) which are promising for enhanced light emission, efficient solar energy harvesting, ultra-sensitive biosensing, and optical cloaking. To date, materials research and device fabrication have focused nearly exclusively on silver and gold nanoparticle dispersions in two dimensions; these arrays exhibit plasmon resonances limited to visible wavelengths. Recently, we demonstrated a novel method to assemble high-quality gallium nanoparticle arrays with surface plasmon resonances tunable from the infrared to visible wavelength range. In this summer project, we explore the influence of gallium nanoparticle arrays on the properties of compound semiconductor solar cells, using a combination of electromagnetic simulations, molecular-beam epitaxy, atomic-force microscopy, and optical spectroscopy.

MSE Project #14: Enhancing p-type Doping of GaN for Power Electronics: A Combined Computational-Experimental Approach
Faculty Mentor: Rachel Goldman, [email protected]
Prerequisites:
- A strong interest in experimental science and/or engineering is required.
- Completion of Introductory Chemistry and Physics Labs is preferred but not required.
Project Description:
Although silicon-based electronics are used to power light-emitting diodes and electric vehicles, their utility in high power applications is limited by a low breakdown voltage. Wide bandgap semiconductors, such as gallium nitride and related alloys, have been proposed as alternatives, but the effective p-type doping at high concentrations remains elusive. For example, Mg dopant activation following ion implantation, selective diffusion, and metalorganic vapor deposition requires high-temperature annealing which may disrupt the active device structure. In the case of molecular beam epitaxy, surfactants and co-dopants such as O and Si have been explored, but the concentration of substitutional Mg is often limited, leading to limited p-type doping efficiency. Here, we are developing a novel approach to enhance the p-type doping of GaN and related alloys.
Methodology: The project involves a combined computational-experimental approach consisting of focused-ion- beam (FIB) nano-implantation of Mg in GaN during molecular-beam epitaxy (MBE), followed by computational and experimental ion channeling studies of the Mg incorporation mechanisms. Possible projects include the following:
- Development of a modified Mg-Ga alloy source for focused-ion-beam nano-implantation
- Ion channeling measurements of doping and point defects in GaN and related alloys
- Monte Carlo-Molecular Dynamics simulations of doping and point defects in GaN and related alloys
Research Mode: In Lab
