Analytical Studies of the Magnetic Domain Wall Structure in the presence of Non-uniform Exchange Bias
Yee-Mou Kao, Chi-Ho Cheng
The pinning phenomena of the domain wall in the presence of exchange bias is studied analytically. The analytic solution of the domain wall spin configuration is presented. Unlike…
Sense current dependent coercivity and magnetization relaxation in Gd-Fe-Co Hall bar
Ramesh Chandra Bhatt, Chun-Ming Liao, Lin-Xiu Ye +3
The understanding of the characteristics of a magnetic layer in a different environment is crucial for any spintronics application. Before practical applications, thorough scrutiny…
Biaxial strain tuning of interlayer excitons in bilayer MoS2
Felix Carrascoso, Der-Yuh Lin, Riccardo Frisenda +1
We show how the excitonic features of biaxial MoS2 flakes are very sensitive to biaxial strain. We find a lower bound for the gauge factors of the A exciton and B exciton of (-41 +…
Vibrational Spectra of Pb2Bi2Te3, PbBi2Te4 and PbBi4Te7 Topological Insulators: Temperature Dependent Raman and Theoretical Insight from DFT Simulations
Priyanath Mal, Ganesh Bera, G. R. Turpu +5
We present temperature dependent frequency shift and line broadening of phonon modes by insertion of atomic layers of Pb and PbTe in the prototype 3D topological insulator Bi2Te3,…
A versatile scanning photocurrent mapping system to characterize optoelectronic devices based on 2D materials
Christoph Reuter, Riccardo Frisenda, Der-Yuh Lin +3
The investigation of optoelectronic devices based on two-dimensional materials and their heterostructures is a very active area of investigation with both fundamental and applied a…
Gate Tunable Photovoltaic Effect in MoS2 vertical P-N Homostructures
Simon A. Svatek, Elisa Antolin, Der-Yuh Lin +8
P-n junctions based on vertically stacked single or few layer transition metal dichalcogenides (TMDCs) have attracted substantial scientific interest. Due to the propensity of TMDC…
Large amplitude vortex gyration in Permalloy/BiSe-like heterostructures
P. N. Skirdkov, K. A. Zvezdin, A. D. Belanovsky +4
We consider the excitation of large amplitude gyrotropic vortex core precession in a Permalloy nanodisk by the torques originating from the in-plane microwave current flowing along…
Electrical control and interaction effects of the RKKY interaction in helical liquids
Yu-Wen Lee, Yu-Li Lee
We study the RKKY interaction mediated by the helical edge states of a quantum spin Hall insulator in the presence of the Rashba spin-orbital coupling induced by an external electr…
Experimental determination of the elastic cotunneling rate in a hybrid single-electron box
Chia-Heng Sun, Po-Chen Tai, Jheng-An Jiang +3
We report measurements of charge configurations and charge transfer dynamics in a hybrid single-electron box composed of aluminum and copper. We used two single-electron transistor…
Electrical transport through a quantum dot side-coupled to a topological superconductor
Yu-Li Lee
We propose to measure the differential conductance as a function of the bias for a quantum dot side-coupled to a topological superconductor to detect the existence of the c…
Observation of fluctuation-induced tunneling conduction in micrometer-sized tunnel junctions
Yu-Ren Lai, Kai-Fu Yu, Yong-Han Lin +2
Micrometer-sized Al/AlO/Y tunnel junctions were fabricated by the electron-beam lithography technique. The thin ( 1.5--2 nm thickness) insulating AlO layer was…
Bending-wave Instability of a Vortex Ring in a Trapped Bose-Einstein Condensate
T. -L. Horng, S. -C. Gou, T. -C. Lin
Based on a velocity formula derived by matched asymptotic expansion, we investigate the dynamics of a circular vortex ring in an axisymmetric Bose-Einstein condensate in the Thomas…
Quantum dynamics of tunneling between ferromagnets
Yu-Li Lee, Yu-Wen Lee
We study the Josephson-like spin currents between two ferromagnetic metals by deriving the effective action of the junction. A DC spin Josephson current with the full O(3) symmetry…
Exact Eignstates for Trapped Weakly Interacting Bosons in Two Dimensions
Wen-Jui Huang
A system of N two-dimensional weakly interacting bosons in a harmonic trap is considered. When the two-particle potential is a delta function Smith and Wilkin have analytically pro…
