Understanding Polaronic Transport in Anatase TiO2 Films by Combining Precise Synthesis and First-Principles Many-Body Theory
F. Liu, Z. Yang, Y. Luo +8
In complex oxides, charge carriers often couple strongly with lattice vibrations to form polarons-entangled electron-phonon quasiparticles whose transport properties remain difficu…
Machine Learning-Assisted Nano-imaging and Spectroscopy of Phase Coexistence in a Wide-Bandgap Semiconductor
Alyssa Bragg, Fengdeng Liu, Zhifei Yang +10
Wide bandgap semiconductors with high room temperature mobilities are promising materials for high-power electronics. Stannate films provide wide bandgaps and optical transparency,…
Strain-Stabilized Interfacial Polarization Tunes Work Function Over 1 eV in RuO2/TiO2 Heterostructures
Seung Gyo Jeong, Bonnie Y. X. Lin, Mengru Jin +14
Interfacial polarization-charge accumulation at the heterointerface-is a well-established tool in semiconductors, but its influence in metals remains unexplored. Here, we demonstra…
Ferroelectric Switching in Hybrid Molecular Beam Epitaxy-Grown BaTiO3 Films
Anusha Kamath Manjeshwar, Zhifei Yang, Chin-Hsiang Liao +4
Molecular beam epitaxy (MBE) is a promising synthesis technique for both heterostructure growth and epitaxial integration of ferroelectric BaTiO3. However, a direct measurement of…
Metallicity and Anomalous Hall Effect in Epitaxially-Strained, Atomically-thin RuO2 Films
Seung Gyo Jeong, Seungjun Lee, Bonnie Lin +14
The anomalous Hall effect (AHE), a hallmark of time-reversal symmetry breaking, has been reported in rutile RuO2, a debated metallic altermagnetic candidate. Previously, AHE in RuO…
High-Mobility Carriers in Epitaxial IrO2 Films Grown using Hybrid Molecular Beam Epitaxy
Sreejith Nair, Zhifei Yang, Kevin Storr +1
Binary rutile oxides of 5d metals such as IrO2, stand out as a paradox due to limited experimental studies despite the rich predicted quantum phenomena. Here, we investigate the el…
Deep-ultraviolet transparent conducting SrSnO3 via heterostructure design
Fengdeng Liu, Zhifei Yang, David Abramovitch +4
Exploration and advancements in ultra-wide bandgap (UWBG) semiconductors are pivotal for next-generation high-power electronics and deep-ultraviolet (DUV) optoelectronics. A critic…
Thickness-dependent insulator-to-metal transition in epitaxial RuO2 films
Anil Kumar Rajapitamahuni, Sreejith Nair, Zhifei Yang +4
Epitaxially grown RuO2 films on TiO2 (110) exhibit significant in-plane strain anisotropy, with a compressive strain of - 4.7% along the [001] crystalline direction and a tensile s…
