Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements
Young-Hoon Kim, Reza Ghanbari, Min-Hyoung Jung +3
Twisted oxide membranes represent a promising platform for exploring moire physics and emergent quantum phenomena. However, the presence of amorphous interfacial dead layers in con…
Mesoscopic Helices of Polar Domains in a Quadruple Perovskite
Yang Zhang, Mingyu Xu, Jie Li +4
A significant effort in condensed matter physics is dedicated to the search for exotic arrangements of electric dipoles in crystals. Non-collinear dipolar arrangements mimicking ma…
Real Space Visualization of Order-Disorder Transition in BaTiO3
Yang Zhang, Xiaoming Shi, Suk Hyun Sung +4
Ferroelectricity in BaTiO3 was observed nearly eighty years ago, but the mechanism underlying its ferroelectric-paraelectric phase transition remains elusive. The order-disorder tr…
Inverse Melting of Polar Order in Chemically Substituted BaTiO3
Yang Zhang, Suk Hyun Sung, Colin B. Clement +2
In many condensed matter systems, long range order emerges at low temperatures as thermal fluctuations subside. In the presence of competing interactions or quenched disorder, howe…
