Photothermally induced, reversible phase transition in methylammonium lead triiodide
Shunran Li, Zhenghong Dai, Conrad A. Kocoj +3
Metal halide perovskites (MHPs) are known to undergo several structural phase transitions, from lower to higher symmetry, upon heating. While structural phase transitions have been…
Scalable production of single 2D van der Waals layers through atomic layer deposition: Bilayer silica on metal foils and films
Gregory S. Hutchings, Xin Shen, Chao Zhou +10
The self-limiting nature of atomic layer deposition (ALD) makes it an appealing option for growing single layers of two-dimensional van der Waals (2D-VDW) materials. In this paper…
Two-Dimensional Transition Metal Silicate Formed on Ru (0001) by Hydrogenation
Kayahan Saritas, Nassar Doudin, Eric I. Altman +1
Bottom-up synthesis of two-dimensional transition-metal silicates has been challenging due to strong overlayer-substrate interactions, which prevents the exfoliation of the overlay…
Magnetism and Piezoelectricity in Stable Transition Metal Silicate Monolayers
Kayahan Saritas, Nassar Doudin, Eric I. Altman +1
Two-dimensional van der Waals (2D vdW) materials that display ferromagnetism and piezoelectricity have received increased attention. Despite numerous 2D materials have so far been…
Suppression of the Spectral Weight of Topological Surface States on the Nanoscale via Local Symmetry Breaking
Omur E. Dagdeviren, Subhasish Mandal, Ke Zou +7
In topological crystalline insulators the topological conducting surface states are protected by crystal symmetry, in principle making it possible to pattern nanoscale insulating a…
Suppression of magnetoresistance in thin flakes by surface oxidation
J. M. Woods, J. Shen, P. Kumaravadivel +7
Recent renewed interest in layered transition metal dichalcogenides stems from the exotic electronic phases predicted and observed in the single- and few-layer limit. Realizing the…
The role of double TiO2 layers at the interface of FeSe/SrTiO3 superconductors
Ke Zou, Subhasish Mandal, Stephen Albright +14
We determine the surface reconstruction of SrTiO3 used to achieve superconducting FeSe films in experiments, which is different from the 1x1 TiO2 terminated SrTiO3 assumed by most…
Imaging the buried MgO/Ag interface: formation mechanism of the STM contrast
Andrei Malashevich, Eric I. Altman, Sohrab Ismail-Beigi
Scanning tunneling microscopy (STM) provides real-space electronic state information at the atomic scale that is most commonly used to study materials surfaces. An intriguing exten…
Exchange bias and interface electronic structure in Ni/Co3O4(011)
C. A. F. Vaz, E. I. Altman, V. E. Henrich
A detailed study of the exchange bias effect and the interfacial electronic structure in Ni/Co3O4(011) is reported. Large exchange anisotropies are observed at low temperatures, an…
Experimental study of the interfacial cobalt oxide in Co3O4/a-Al2O3(0001) epitaxial films
C. A. F. Vaz, D. Prabhakaran, E. I. Altman +1
A detailed spectroscopic and structural characterization of ultrathin cobalt oxide films grown by O-assisted molecular beam epitaxy on a-Al2O3(0001) single crystals is reported. Th…
Interface and electronic characterization of thin epitaxial Co3O4 films
C. A. F. Vaz, H. -Q. Wang, C. H. Ahn +10
The interface and electronic structure of thin (~20-74 nm) Co3O4(110) epitaxial films grown by oxygen-assisted molecular beam epitaxy on MgAl2O4(110) single crystal substrates have…
