For his work in discovering new phenomena and developing novel tools to probe and control materials, Professor of Physics Kenneth Burch has been named a fellow of the American Physical Society, the world鈥檚 largest organization of professionals in physics and related disciplines.
鈥淚t is a real honor to be included in such a distinguished set of physicists,鈥� Burch said. 鈥淚鈥檓 very grateful to the wonderful students, colleagues and collaborators over the years that contributed to our success.鈥�
The honor is highly selective, with fewer than 250 members nominated annually from the organization鈥檚 approximately 50,000 members. Burch was nominated for the honor by the Condensed Matter Physics division of the society, according to a letter from APS President Frances Hellman, who noted Burch is being recognized: 鈥淔or pioneering studies of two-dimensional materials including van der Waals heterostructures and developing the methods used to created layered van der Waals heterostructures.鈥�

Van der Waals crystals, which are held together by friction, have been used to isolate single-atom-thick layers of material used to detect new physical effects and applications. The most common example is graphene, which is composed of atom-thick layers which can be peeled off by applying a piece of clear household adhesive tape.
Burch has used this procedure to create new interfaces between highly distinct materials. Specifically he produced the thinnest and most uniform samples, then combined them to serve as a platform upon which to create unique states with a range of physical properties. The two- dimensional magnetic crystals are being explored for a range of uses, including the potential to use their electronic properties鈥攎ost notably 鈥渟pin鈥濃�攖o advance quantum computing, 鈥渟pintronics," magnetic and optical sensors, and high temperature superconductors.
"The work being cited includes our efforts to create novel physical phases and unleash new phenomena through combined optical studies and creation of new devices,鈥� Burch said.
That includes his team鈥檚 discoveries of the Collosal Bulk Photovoltaic effect鈥攁mong the largest conversions of light to electricity of any material鈥攁nd the recent finding of an Axial Higgs Mode in a two-dimensional charge density wave system, a previously undetectable quantum excitation Burch describes as a magnetic relative of the mass-defining Higgs Boson particle.
鈥淲e have also uncovered new superconducting states and developed a novel biosensing platform based on graphene single atomic layer of carbon,鈥� Burch said. 鈥淭o achieve this the group has created a cleanroom in a glovebox, the first of its kind to allow fabrication of nanoscale devices entirely in an inert atmosphere. This enabled cutting edge and rapid progress by postdocs, graduate and undergraduate students in fabricating and measuring nanomaterials.鈥�
With Burch鈥檚 selection, six current and two former 艾可直播 College 艾可直播have been named APS Fellows, including six from the Physics Department and two from the Chemistry Department.
"This prestigious distinction is a well-earned recognition of Prof. Burch鈥檚 highly productive and creative research program, and reflects the commitment of our department and 艾可直播 College to both fundamental and applied science," said Professor of Physics and Department Chair Michael Graf.
