Reducing switching losses through MOSFET-IGBT combination [PDF]

open access: yes, 2008
This paper introduces a configuration aimed at switching losses reduction trough a power leg constructed by combining a MOSFET and an IGBT. The combined use of these different switches leads to the turn-on losses reduction trough the use of the faster ...

Reciprocity in reflection and transmission: what is a "phonon diode"?

open access: yes, 2012
The newly popular topic of "phonon diodes" is discussed in the context of a broader issue of reciprocity in reflection/transmission (R-T) of waves. We first review a theorem well known in electromagnetism and optics but underappreciated in acoustics and ...

A sub-1-V Bandgap Voltage Reference in 32nm FinFET Technology [PDF]

open access: yes, 2009
The bulk CMOS technology is expected to scale down to about 32nm node and likely the successor would be the FinFET. The FinFET is an ultra-thin body multi-gate MOS transistor with among other characteristics a much higher voltage gain compared to a ...

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,

Means for phase locking the outputs of a surface emitting laser diode array [PDF]

open access: yes, 1987
An array of diode lasers, either a two-dimensional array of surface emitting lasers, or a linear array of stripe lasers, is phase locked by a diode laser through a hologram which focuses the output of the diode laser into a set of distinct, spatially ...

The Physics of Mind-Matter Interaction at a Distance [PDF]

open access: yes, 2017
The aim of this work is identification and localisation of the interaction between mind and matter, specifically with respect to random number generators, and identification of the type of energy that can alter the degree of randomness of bit-string ...

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

open access: yesAdvanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Electric Field‐Dependent Conductivity as Probe for Charge Carrier Delocalization and Morphology in Organic Semiconductors

open access: yesAdvanced Functional Materials, EarlyView.
Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

Applications of combined MOSFET-IGBT power leg with reduced switching losses [PDF]

open access: yes, 2008
This paper discusses power legs built upon the combination of a MOSFET and an IGBT. The suggested combined use of those different switches is intended to be applied in PWM controlled single and three phase inverters.
