Quantum at the macroscale: superlattices for energy and electronic devices

In seminar this week we have the pleasure of hearing from the recipient of this year's Young Alumni Award, Kwabena Bediako.
"Very few Calvin students end up as professors at the top R1 institutions in the nation. Kwabena has achieved that at UC Berkeley. He has done incredible science both at Harvard and UC-Berkeley. Two of his research mentees are assistant professors at MIT and Princeton. He would be an inspiration for our international students at Calvin! Kwabena came to Calvin from Ghana as an international student following his brother's (Yaw Bediako) footsteps. Kwabena was an undergraduate researcher in Doug Vander Griend's lab."
Title: Quantum at the macroscale: superlattices for energy and electronic devices
Abstract: The periodicity of crystalline solids dictates the extended electronic wavefunctions that give rise to a material鈥檚 physical and chemical properties. When atomically thin crystals are modified by additional long-range periodic modulations鈥攅ven subtle ones鈥攖he impacts on the quantum behavior of these materials can be pronounced and manifest in macroscale properties. This talk will discuss how superlattice engineering of two-dimensional quantum materials has given us new insights into electrochemical reactions that underpin energy conversion/storage and opened up routes to the synthesis of magnetic materials that hold promise for electronic devices of the future.
