Photoconductive terahertz generation from textured semiconductor materials
Photoconductive (PC) terahertz (THz) emitters are often limited by ohmic loss and Joule heating-as these effects can lead to thermal runaway and premature device breakdown. To address this, the proposed work introduces PC THz emitters based on textured InP materials. The enhanced surface recombination and decreased charge-carrier lifetimes of the textured InP materials reduce residual photocurr...
متن کاملNanomechanical Optical Fiber with Embedded Electrodes Actuated by Joule Heating
Nanomechanical optical fibers with metal electrodes embedded in the jacket were fabricated by a multi-material co-draw technique. At the center of the fibers, two glass cores suspended by thin membranes and surrounded by air form a directional coupler that is highly temperature-dependent. We demonstrate optical switching between the two fiber cores by Joule heating of the electrodes with as lit...
متن کاملAnalysis of Planar Circular Interdigitated Electrodes for Electroporation
in this work, designs for planar, interdigitated circular electrode structures for cell membrane permeabilization procedures are analysed using finite element method analysis. The generated electric field intensity, homogeneity and the Joule heating are evaluated. The optimal electrode configuration for successful transfection procedures is investigated. Based on the simulation results, an opti...
متن کاملPicosecond microwave pulse generation
Picosecond duration X-band microwave pulses have been generated using a laser-activated photoconductive switch. These pulses have been used to observe the microwave reflection from optically excited germanium. The reflection measurements indicate that the microwave pulse has a full width at half-maximum of 50 ps and is synchronized with picosecond precision to the laser pulse. A high-resolution...
متن کاملDirect and contactless electrical control of temperature of paper and textile foldable substrates using electrospun metallic-web transparent electrodes
Multiple and complex functionalities are a demand nowadays for almost all materials, including common day-to-day materials such as paper, textiles, wood, etc. In the present report, the surface temperature control of different types of materials, including paper and textiles, was demonstrated by Joule heating of metallic-web transparent electrodes both by direct current and by RF induced eddy c...
