Project Goals and Description:
This year-long undergraduate research project will support the development of quantum device test structures for studying electron-phonon interactions in silicon. The student will focus on fabricating thin-film capacitors on silicon MOSFET-based substrates using electron-beam evaporation and/or sputtering techniques. These capacitors are a key component in prototype devices used to explore electrically detected magnetoresonance, a method that sheds light on the physics of spins in silicon quantum dots. Silicon quantum dot based spin qubits are important contenders for the next generation "hot" qubits that can operate at elevated temperatures, outside a dilution refrigerator. The student will gain hands-on experience in nanofabrication, thin-film deposition, and electrical characterization using tools such as a probe station and LCR meter, while also learning to interpret capacitance and leakage current data in the context of device performance and reliability.

MENTORING PLAN
We complete an IDP detailing student goals at the beginning of the semester. I have a weekly group meeting in which the students will present their results. In addition, I have pre-determined lab times during which I am available to help with lab problems. My PhD students and post-doc help with mentoring the student also.
Preferred Student Status
Sophomore
