A new MOS gate-controlled power switch with a very low onresistance is described. The fabrication process is similar to that of an n-channel power MOSFET but employs an n--epitaxial layer grown on a p+ substrate. In operation, the epitaxial region is conductivity modulated (by excess holes and electrons) thereby eliminating a major component of the on-resistance. For example, on-resistance valu...

Hydrogenated amorphous silicon (a-Si:H) has been already considered for the objective of passive optical elements, like waveguides and ring resonators, within photonic integrated circuits at λ = 1.55 μm. However the study of its electro-optical properties is still at an early stage, therefore this semiconductor in practice is not considered for light modulation as yet. We demonstrated, for the ...

In this paper we explore a multi-step synthetic strategy toward fabrication of monolayer-modified Si(100) electrodes that can be electrochemically switched. The synthetic scheme is modular and benefits from an established intramolecular lactonization scheme of benzoquinone analogs. A redox-tagged pendant group can be released from the surface such as to allow for in situ monitoring of the switc...

(b) (c) Abstract—Computers are getting faster and faster every year and so is the transistors count. The capabilities of digital electronic devices have excelled during the past 40 years but since 2010 the pace has slowed down because of no reduction in semiconductor gate delays and them power required to drive them. This has led to the emergence of new technology of photonic switches and gates...

Due to the lower tensile low-distortion overall output voltage with power switch stress, multilevel inverter (MLI) is popular. MLI does however have several semiconductor switches and therefore increases complexity of switches. New symmetric asymmetric structures are proposed in this report. According experts, require less controlled switches, diodes, condensers than both conventional recently ...

This work proposes a high step-up interleaved dc/dc topology utilizing a VM (voltage multiplier) cell suitable for PV applications. The VM cells D/C (Diode/Cap.) are cascaded among the phases to approach a high voltage gain. Besides, the voltage converting ratio of the presented structure can be improved by extending the VM cells and it also leads to drop in the normalized voltage stress throug...

The inability to efficiently tune the optical properties of waveguiding structures has been one of the major hurdles for the future scalability of integrated photonic systems. In silicon photonics, although dynamic tuning has been achieved with various mechanisms, even the most effective thermo-optic effect offers a refractive index change of only 1.86 × 10 K. To enhance this small change, ligh...

Abstract To investigate the thermal-switching properties of Pd-catalyzed Ni–Mg alloy films, we conducted in situ analyses films’ electrical, optical, and thermal through hydrogen gasochromic reactions. These reactions allow films to reversibly switch between metallic (dehydride) semiconductor (hydride) phases. The conductivities states were found be 14 1.0 W m −1 K , respectively. By applying W...

Power switches are used as part of power-gating technique to reduce leakage power of a design. To the best of our knowledge, this is the first work in open-literature to show a systematic diagnosis method for accurately diagnosing power switches. The proposed diagnosis method utilizes recently proposed DFT solution for efficient testing of power switches in the presence of PVT variation. It div...

Induction heating (IH) technology is very popular in domestic applications because of its efficiency and safe operating properties. Resonant inverter circuits are widely used IH systems owing to their high soft-switching capability. Among the resonant inverters systems, single-switch quasi-resonant topology generally preferred for low-cost low-output-power applications. Despite advantage invert...
