Nanoscale Polar Landscapes in Quantum Paraelectric SrTiO3
Yang Zhang, Suk Hyun Sung, Nishkarsh Agarwal +5
SrTiO3 is a textbook quantum paraelectric, with ferroelectricity purportedly suppressed by quantum fluctuations of ionic positions down to the lowest temperatures. The precise real…
Helium-Cooled Cryogenic STEM Imaging and Ptychography for Atomic-Scale Study of Low-Temperature Phases
Noah Schnitzer, Mariana Palos, Geri Topore +7
Much of the exotic functionality of prime interest in quantum materials emerges from structural and electronic ground states that can only be accessed at cryogenic temperatures. Un…
Melting point depression of charge density wave in 1T-TiSe due to size effects
Saif Siddique, Mehrdad T. Kiani, Omri Lesser +13
Classical nucleation theory predicts size-dependent nucleation and melting due to surface and confinement effects at the nanoscale. In correlated electronic states, observation of…
Liquid Helium Cryogenic TEM below 1 Ã
Suk Hyun Sung, Maya Gates, Nishkarsh Agarwal +10
Next-generation cryogenic transmission electron microscopes (TEM) aim to achieve high-resolution imaging at ultracold sample temperatures (< 90 K) and over extended hold times. Low…
