What KNDL Does
The mission of the Koester NanoDevice Laboratory (KNDL) is to research new solid-state device concepts spanning multiple material platforms and applications. The lab works on advanced electronic devices, including scaled metal-oxide semiconductor field-effect transistors (MOSFETs) for end-of-roadmap ultra-large scale integration (ULSI) microchip applications, cryogenic MOSFETs, high-speed devices, and high-power transistors. KNDL also explores novel optoelectronic devices, with an emphasis on advanced photodetectors, and optical modulators. In the past, the lab has also explored the spintronic applications of graphene for use in miniaturized magnetic field sensors in hard drive read heads. KNDL has developed new types of biosensors, including glucose monitors, breath sensors, and dosimeters for radiation cancer therapy. Finally, the lab is developing technologies for three-dimension heterogeneous integration (3DHI) and advance packaging for high-bandwidth memory, and hybrid power electronic circuits.
How KNDL Works
KNDL explores these novel devices mainly through the use of new materials. There is a strong focus on two-dimensional (2D) materials, including graphene, and transition metal dichalcogenides (TMDs), and the lab has dedicated growth, transfer, and assembly capabilities for these materials. Through the lab's many collaborators, KNDL is also exploring numerous oxide-based materials including rutile germanium oxide and hafnium-based ferroelectrics. This work has been supported by a wide range of sources, including government, industry, and charitable foundations.
KNDL pursues its research goals through theoretical analysis, device design and simulation, process development, fabrication, and characterization. All group members fabricate devices in the Notre Dame Nanofabrication Facility (NDNF), and gain a full range of skills necessary to pursue a career in industry or academia.
