Multiferroic heterostrcture composed of ferromagnetic and ferroelectric phase has recently attracted ever-increasing amount of interest due to its strong magnetoelectric coupling at room temperature [1-3]. In particular, the strain-mediated magnetoelectric (ME) coupling arising from the combined piezoelectric and magnetoelastic effect has shown a large modification of the magnetic anisotropy of the...
Terahertz photoconductive antenna arrays with interdigitated electrodes are laid down on GaAs substrates in which different geometries are assessed for their ability to enhance performance of a time-domain spectrometer (TDS) system.
We model and simulate the microscopic electromagnetic fields induced by ion currents passing through nanochannels based on membrane currents data obtained by A. L. Hodgkin and A. F. Huxley in their experiments on squid giant axons. We find that compared with magnetic field, electric field affects ion motion much more considerably, and we further discuss the effect of such electric fields on the spread...
This paper summarizes our recent investigations of nano-wire n type tunneling field effect transistor (n-TFET) reliability by experimental measurements and physical analysis [1-3]. Large PBTI and HC degradations which are very different from those in conventional n-MOSFETs were observed. The results are interpreted by different degradation mechanism in TFET.
This paper reports electric properties calculation of a composite housed SF6 insulated bushing based on the finite element method. After introducing different stages of electric field distribution under DC voltage, the finite element method and boundary conditions are described. The electric field distribution, time constant of transmission from conductive distribution to resistive distribution are...
Summary form only given. Terahertz radiation, which ranges from 0.1 THz to 10 THz, has received substantial interests in recent years. The conventional vacuum electronics technology has the potential to supply high enough powers to underpin many exciting and emerging THz applications. Klystrons have been designed to generate THz radiation. This vacuum device requires a very small sized RF circuit...
Nanosecond pulsed electric fields have demonstrated remarkable potential as tumor therapy. The application of 300-ns pulses with amplitudes of 40-50 kV/cm to melanomas grown in mice caused complete remission of the tumors. It is believed that the primary process that kills the tumor cells is the induction of apoptosis. Electrical models predict that for the application of shorter pulses, higher field...
The basic operation principle of microwave oscillators, such as magnetrons, is based on the motion of electrons under a combined influence of electric and magnetic fields. In such process, the DC energy is converted into the RF energy via the interaction process between the electrons and the surrounding electromagnetic field. This nonlinear process provides sufficient conditions in generating rather...
A novel, high-efficiency detector for acetic acid vapor in ambient air is described. The design uses carbon nanotubes, grown on silicon substrate by CVD. Application of a positive bias to the carbon nanotubes generates electric fields sufficient to field-ionize passing gas-phase atoms especially for organic vapor. Under the pressure of one standard atmospheric pressure (atm), the detector was demonstrated...
