Memory in strain-tuned insulator-metal-insulator sequence of transitions after photoexcitation in the Mott material V2O3
O. Yu. Gorobtsov, Y. Kalcheim, Z. Shao +9
Memory effects during metal-insulator transitions in quantum materials reveal complex physics and potential for novel electronics mimicking biological neural systems. Nonetheless,…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
Critical slowing of the spin and charge density wave order in thin film Cr following photoexcitation
Sheena K. K. Patel, Oleg Yu. Gorobtsov, Devin Cela +11
We report on the evolution of the charge density wave (CDW) and spin density wave (SDW) order of a chromium film following photoexcitation with an ultrafast optical laser pulse. Th…
Spontaneous supercrystal formation during a strain-engineered metal-insulator transition
O. Yu. Gorobtsov, L. Miao, Z. Shao +13
Mott metal-insulator transitions possess electronic, magnetic, and structural degrees of freedom promising next generation energy-efficient electronics. We report a previously unkn…
Real-space imaging of polar and elastic nano-textures in thin films via inversion of diffraction data
Ziming Shao, Noah Schnitzer, Jacob Ruf +13
Exploiting the emerging nanoscale periodicities in epitaxial, single-crystal thin films is an exciting direction in quantum materials science: confinement and periodic distortions…
X-ray Nano-imaging of Defects in Thin Film Catalysts via Cluster Analysis
Aileen Luo, Oleg Yu. Gorobtsov, Jocienne N. Nelson +9
Functional properties of transition-metal oxides strongly depend on crystallographic defects. In transition-metal-oxide electrocatalysts such as SrIrO3 (SIO), crystallographic latt…
