Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices
Advanced Electronic Materials, EarlyView.Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Advanced Intelligent Discovery, EarlyView.We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Chip‐Scale Terahertz Sensing Driven by Supercoupling Induced Transparency in Topological Cavities
Laser &Photonics Reviews, EarlyView.Supercoupling‐induced transparency (SIT) in topological cavities enables sensitive terahertz sensing on a chip. Strong field confinement and slow light response enhance interactions with thin films, enabling thickness detection through resonance shifts and group delay changes.

Phase Noise Reduction in a VHF MEMS-CMOS Oscillator Using Phononic Crystals
IEEE Journal of the Electron Devices Society, 2016 This paper presents experimental results showing reduced phase noise in a very high frequency band microelectromechanical systems (MEMS) oscillator. This has been achieved by engineering the embedded MEMS resonator with phononic crystal structures.
