Flexible and transparent electronic optoelectronic devices have attracted more research interest due to their potential applications in developing portable, wearable, low-cost, implantable devices. We fabricated studied high-performance flexible CdSe nanobelt (NB)/graphene Schottky junction self-powered photovoltaic detectors for the first time. Under 633 nm light illumination, typical photosensitivity responsivity of are about 1.2 × 105 8.7 A W−1, respectively. 3500 Hz switching frequency,...
We fabricated fully epitaxial magnetic tunnel junctions with LiF barriers on Si (100) substrates high-vacuum electron-beam deposition. By changing the thickness of barrier, magnetoresistance up to 90% at 77 K (17% room temperature) was observed tLiF = 2.8 nm. The ratio as a function barrier shows similar trend that in using MgO barriers. There is rapid decrease increasing bias-voltage and temperature, indicating presence imperfections
Currently, numerical methods used for the coupling analysis of power line network, integrating structural features curve and multiorientations, are still rare. An efficient time-domain hybrid method consisting finite-difference (FDTD) method, transmission (TL) equations Agrawal model, coordinate transform, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</i> -parameter cascade techniques is presented in this work, which can realize...
Resonant tunneling can lead to inverse tunnel magnetoresistance when impurity levels rather than direct dominate the transport process. We fabricated hybrid magnetic junctions of CoFe/LiF/EuS/Ti, with an epitaxial LiF energy barrier joined a polycrystalline EuS spin-filter bar-rier. Due water solubility LiF, devices were fully packaged in situ. The showed sizeable positive TMR up 16% at low bias voltages but clearly inverted higher voltages. inversion depends sensitively on thickness and...
In order to solve the problem of slow computation speed and difficulty in solving electromagnetic response electrically large targets by using finite difference frequency domain (FDFD) serial method, a parallel FDFD calculation method based on MPI memory sharing mechanism is proposed. complex sparse matrix allocated each sub process row, intermediate used all processes stored shared reduce consumption. The conjugate gradient obtain solution equation. Numerical results show correctness...
We theoretically and numerically studied the band structure spin transport of electrons subject to a superlattice where magnetic semiconductor layers lie between normal form periodic spin-filter tunnel barriers. In this alternately deposited structure, due induced periodicity envelope wavefunctions, there are additional allowed forbidden energy regions established, i.e. forming minibands that far narrower than conventional conduction bands. The number thickness stacked potential profiles can...
We created epitaxial magnetic tunnel junctions of FeCo/MgO/EuS on MgO buffered Si (100). Tunnel magnetoresistance reached up to 64% at 4.2 K. An unexpected fast drop was recorded for thickness above 1 nm, which is attributed the forced nonspecular conductance across EuS conduction band minimum located X points, rather than desired ∆1 centered around Γ point.
This paper presents a dual polarized antenna with high isolation for wide-angle scanning phased array radar. For the proposed antenna, electronic and magnetic resources are realized through printed monopole slot ring respectively. A metal reflector ground was introduced to achieve unidirectional pattern, ratio of front back pattern improved. The fed by coaxial electromagnetic couplings, radiation fields emitted current resource approximately orthogonal each other among large space ranges....
