Conventional semiconductor heterojunctions and homojunctions are foundational building blocks of optoelectronic devices including solar cells and light-emitting diodes. Non-centrosymmetric two-dimensional (2D) materials enable the engineering of mixed-dimensional heterostructures with complex optoelectronic properties, such as a polarization-dependent photoresponse.
Moiré quantum materials host exotic electronic phenomena through enhanced internal Coulomb interactions in twisted two-dimensional heterostructures. When combined with the exceptionally high electrostatic control in atomically thin materials, moiré heterostructures have the potential to enable next-generation electronic devices with unprecedented functionality.
Affiliates' Day was an all-day event for all CMI community members to meet and engage with relevant and interested industrial affiliates.
A short course for high school instructors with activities that can be taken back to their own classrooms was hosted by the CMI in July 2024. The intent was to share learning and instructional content based on the same materials and concepts actively being developed in cutting-edge research labs across the globe but with components accessible, usable, and understandable at the high school level.
The CMI-MRSEC Research Experiences for Youth (REY) program is a 7-week residential program for high school juniors. Our Summer 2024 cohort of 9 explored UM’s college of engineering campus through lab visits and Ann Arbor with their residential coordinators. The REY program culminated with their families joining for the Summer Research Symposium.
The Center for Materials Innovation (CMI) is committed to enhancing diversity and improving educational opportunities across STEM fields that comprise materials research at UM and beyond. CMI programs include professional development components to enhance student experiences and prepare them for transitions through academia, industry, and government.
The Industrial Mentorship Program connects undergraduate students, graduate students and post-doctoral fellows to a PhD level mentor in industry. This program is designed to (i) expose participants to fundamental research as it relates to societal and economic development; (ii) enable them to broaden their networks; and (iii) facilitate a successful transition into the workforce. The Industrial Mentor program entered its sixth program cycle during 2023-2024 and since its inception, 147 students have participated as mentees in the program, with 30 of those from the CIMA PREM at Texas State University.
CDCM’s Research Experiences for Teachers (RET) program engages elementary school teachers in materials research at UT Austin during the summer and has created lasting impact over the past six years. The program aims to increase teacher efficacy in research practices and guide teachers in integrating what they learn into their instructional practice. The end goals are to enhance students’ engagement in science and increase students’ awareness of and interest in STEM fields.
Hydrogels with dynamic linkers have garnered intense interest for applications that require flow, including injectable delivery vehicles and 3D bioprinting inks. However, to fully enable these applications, there remains a need to understand how linking chemistry affects gelation and nonlinear rheological properties. To probe this relationship, UT Austin MRSEC researchers developed synthetic multi-arm polyethylene glycol (PEG) gels linked with dynamic covalent bonds.
UT Austin researchers used polarization-dependent terahertz magnetospectroscopy to observe Zeeman splittings and diamagnetic shifts in a series of Pb1-xSnxTe films, which transition from a topologically trivial insulator to a topological crystalline insulator (TCI) phase as the Sn concentration increases beyond 0.32. This study demonstrates a substantial phonon magnetic moment films in the TCI phase exhibited phonon magnetic moment values significantly larger—by two orders of magnitude—than those in the topologically trivial sample.
