Quantum Materials Interfaces
and Nano Devices Lab

In Korean

Q.MIND Lab is a research group established in January 2024 in the Department of Semiconductor Engineering at the Gwangju Institute of Science and Technology. We all live in a new era of hyper-Moore’s Law, which demands increasing information density, data processing capacity, and energy efficiency within a given wafer footprint, going beyond the traditional approach of shrinking device structure size or increasing the number of transistors. Accordingly, we are focused on contributing to the evolution of device architectures that transcend the current state-of-the-art Silicon technologies, encompassing artificial intelligence and quantum computing, ultimately enabling their integration of monolithic systems into CMOS processes.

(1) Our research group is currently dedicated to laying the foundations as a starting lab. As initial members, you can learn a lot while building the lab and achieve great results with solid support and close care directly from your academic advisor, Prof. Yoon, much more than ever. If you are an ambitious dreamer and want to become a rising scientist or a leading engineer, please do not hesitate to join our group.

(2) Our research aims to explore various quantum materials and the exotic phenomena at their interfaces, fabricate and characterize nanodevices based on them, and achieve large-scale integration and real-world applications. There is a significant difference between discussing a scientific idea and publishing a scientific article. To turn our ideas into an article for each research topic assigned to each member, you will learn [1] device physics fundamental (material property understanding, device structure design, process development-optimization), [2] precision measurement and characterization (property inspection-analysis, performance-reliability-lifetime-yield evaluation, data collection-management-statistics), and [3] application demonstration and verification (operating principle clarification, large-scale integration, commercialization verification).

(3) Our research topics have four categories: [1] artificial intelligence sensors (miniaturized computational spectrometers, optical interconnects, single-pixel imaging via coded apertures, remote gas detectors), [2] more than Moore devices (topological gate dielectrics, topological semimetal contacts, optoelectronic multi-valued logic gates, optoelectronic synapses), [3] electron quantum optics (quantum point contacts, negative refractive Veselago lenses, backscattering suppressed Klein collimators, Aharonov-Bohm interferometers), and [4] quantum phase transitions (van der Waals Josephson junctions, Majorana Fermions, Mott transitions, proximity effect, Stark effect, spin-galvanic effect). These meet hot trends in artificial intelligence semiconductor and quantum computing hardware, providing core technologies for on-device AI, autonomous driving, big data, hyper-connectivity, qubit platforms, etc. Please refer to the Research Topic & Briefing for more details.

(4) Our research methodologies integrate engineering means and goals to form an essential medium that links theories and experiments through various domestic and international academic collaborations. Please take a look at the Research Project & Academic Collaboration for more details.

(5) Our novel devices may lead the next-generation semiconductor industry and potentially solve social problems by offering technical solutions to unemployment, poverty, environmental pollution, climate change, resource shortage, war, aging, etc.

(6) Our group members will receive extensive lessons on [1] balanced weighting for growing as an independent researcher (independence-cooperation system when conducting individual-collaborative research, autonomy-responsibility when dividing roles, creativity-productivity when promoting work, perfection-achievement when producing results, work-life when living in a lab). [2] self-directed training for creative academic activities (setting short-, medium-, and long-term goals, periodic evaluation of achievement and self-reflection, voluntary reinforcement of major foundations and understanding of the latest research trends, contributing to a study atmosphere, and physical-mental health management), and [3] mutual relationship forming to become a researcher that collaborators want to seek out first (strict adherence to research ethics-safety-authenticity, establishment of a culture of respect-trust-consideration, effective communication-feedback, brainstorming new ideas through convergent thinking, raising practical criticism, and positive acceptance).

(7) Our group environment promotes work-life balance, believing that excellent research results are driven by insights and motivations from a balanced life. Please check our contact page for more details. Please check the Contact for more details.
