Probe Ferroelectricity by X-ray Absorption Spectroscopy in Molecular Crystal
Fujie Tang, Xuanyuan Jiang, Hsin-Yu Ko +8
We carry out X-ray absorption spectroscopy experiment at oxygen K-edge in croconic acid (C5H2O5) crystal as a prototype of ferroelectric organic molecular solid, whose electric pol…
Machine-Learning X-ray Absorption Spectra to Quantitative Accuracy
Matthew R. Carbone, Mehmet Topsakal, Deyu Lu +1
The advent of massive data repositories has propelled machine learning techniques to the front lines of many scientific fields, and exploring new frontiers by leveraging the predic…
Classification of Local Chemical Environments from X-ray Absorption Spectra using Supervised Machine Learning
Matthew R. Carbone, Shinjae Yoo, Mehmet Topsakal +1
X-ray absorption spectroscopy is a premier element-specific technique for materials characterization. Specifically, the x-ray absorption near-edge structure (XANES) encodes importa…
Decomposition of La2-xSrxCuO4 into Several La2O3 Phases at Elevated Temperatures in Ultra-High Vacuum inside a Transmission Electron Microscope
Jong Seok Jeong, Wangzhou Wu, Mehmet Topsakal +4
We report the decomposition of La2-xSrxCuO4 into La2O3 and Cu nanoparticles in ultra-high vacuum, observed by in-situ heating experiments in a transmission electron microscope (TEM…
Iron spin crossover and its influence on post-perovskite transitions in MgSiO and MgGeO
Gaurav Shukla, Mehmet Topsakal, Renata M. Wentzcovitch
MgGeO-perovskite is known to be a low-pressure analog of MgSiO-perovskite in many respects, but especially in regard to the post-perovskite transition. As such, investigati…
Monitoring of band gap and magnetic state of graphene nanoribbons through vacancies
M. Topsakal, E. Akturk, H. Sevincli +1
Using first-principles plane wave calculations we predict that electronic and magnetic properties of graphene nanoribbons can be affected by defect-induced itinerant states. The ba…
