Journal ArticleDOI
Preparation and characterization of atomically clean, stoichiometric surfaces of AIN(0001)
W. J. Mecouch,B. Wagner,Z. J. Reitmeier,Robert F. Davis,Chethan Pandarinath,Brian J. Rodriguez,Robert J. Nemanich +6 more
TL;DR: In situ exposure of the (0001) surface of AlN thin films to flowing ammonia at 1120°C and 10−4Torr removes oxygen∕hydroxide and hydrocarbon species below the detectable limits of x-ray photoelectron spectroscopy and decreases the Al∕N ratio from 1.3 to 1.0.
Journal ArticleDOI
Scanning frequency mixing microscopy of high-frequency transport behavior at electroactive interfaces
TL;DR: An approach for high-frequency transport imaging, referred to as scanning frequency mixing microscopy (SFMM), is developed in this article, where two highfrequency bias signals across an electroactive interface results in a low-frequency component due to interface nonlinearity.
Journal ArticleDOI
Controlling the mechanoelasticity of model biomembranes with room-temperature ionic liquids.
TL;DR: This preliminary result points to the potential use of RTILs to control the mechanoelasticity of cell membranes, opening new avenues for applications in bio-medicine and, more generally, bio-nano-technology.
Journal ArticleDOI
Decoupling Mesoscale Functional Response in PLZT across the Ferroelectric-Relaxor Phase Transition with Contact Kelvin Probe Force Microscopy and Machine Learning.

TL;DR: The combination of this multidimensional voltage spectroscopy technique and machine learning allows to identify the origin of the measured functional response and to decouple ferroelectric from electrostatic phenomena necessary to understand the functional behavior of complex, disordered systems like relaxor materials.
Journal ArticleDOI
Direct shape control of photoreduced nanostructures on proton exchanged ferroelectric templates
TL;DR: In this paper, the depth of the proton exchange (PE) in congruent lithium niobate (LiNiobate) was controlled by varying the PE depth from 0.59 to 3.10μm.
