Wim Geerts Scholarship

Major Research interest:

• 3D-printed Magnetic Composites (Magnetic Field Assisted Additive Manufacturing) and methods for application in novel Halbach cylinders in motors, generators, clutches, and permanent magnets.
• Magneto-elastic and Magneto-plastic properties of thin films and composites for application in actuators including artificial muscles. 
• Properties of novel transition metal oxides including the ultra-wide bandgap semiconductors Ga2O3, In2O3, and Al2O3 that are currently explored for application in high power electronics including LED lighting electronics and military radar transmitters. 
• Wide bandgap Organic Perovskite thin films deposited by solvent processing for application in under water and tandem solar cells.

Equipment we use for our Research:

• Measurement techniques available in our laboratory: MO Kerr magnetometry, rotating field magnetostriction measurement technique, van der Pauw four-point probe measurement technique, deep level transient spectroscopy, external quantum efficiency measurements on solar cells, Solar Cell efficiency measurements, IVT measurements.
• Measurement methods we use through SRO and collaboration for our research: SEM/EDAX, XRD, Ellipsometry, Vibrating Sample Magnetometry and torque magnetometry, XPS, AFM, stylus profilometry, Photoluminescence measurements. 
• Deposition methods available in Zakhidov Organics Semiconductor Lab : glovebox cluster including spin coater in wet glovebox and thin film evaporator in dry glovebox for solar cell device stack, water cooled FDM 3D printer for magnetic field assisted additive manufacturing.
• Deposition and manufacturing methods we use through SRO and collaboration for our research: Pulsed Laser Deposition (Dr. Droopad, Electrical Engineering), Twin Screw Extruder (Dr. Tate, Manufacturing and Mechanical Engineering), glovebox and inkjet printers (Dr. Chen, Electrical Engineering).

Research Project Openings for Spring 2024-Fall-2024:

• Development of a setup to measure the magnetostriction properties of magneto-elastomers. 
• Nucleation and Growth of Slot-die printed ultra wide bandgap halide perovskite semicconductors.
• Development of a tableop stress-strain measurement setup for magneto-elastomers.
• MOKE setup that allows for magnetic hysteresis curve measurements on samples that are exposed to a tensile strain.
• DFT calculation on CuI/2D-perovskite/3D-perovskite device stack.
