... wide bandgap material that has some of the desired properties to reduce these losses. Short drift regions can be utilized without reducing the blocking voltage thanks to the extremely high electric field strength. This instantly leads to a smaller on-state voltage drop, but also a reduction in switc ...

Pulsed Plasma Thruster Ignition System: Investigation, Test Design
... the whole ignition subsystem of the PPT is essential. As the spark plug is part of a spacecraft, it must satisfy some essential requirements. It has to be able to work reliably in the space environment, such as vacuum and radiation, and into the thruster environment as well. Considering its location ...

SCANNING TUNNELING SPECTROSCOPY ON ORGANIC MOLECULES A Thesis
... I(V) data from TMXYL-TCNE indicates that the CT complex is an electrical conductor, with a nearly linear I(V) behavior at V=0. When the TCNE molecule is removed, I(V) data from TMXYL-flat indicates that for small voltages (|V| < 0.5V), TMXYL is an electrical insulator. This data combined with the I( ...

... Next, the “myth” of “ground” is explored. While earth ground does indeed exist, so do our misunderstandings of it. In electronics, ground is considered to be a common point, a point of zero potential and an infinite sink of electrons. In reality, most points we consider “grounded” are far from this ...

1 AC Losses in High Temperature Superconductors under non –Sinusoidal Conditions
... AC loss calculation are usually based on consideration of the non-linear Maxwell equations in which a superconductor is simulated by a media with non-linear voltage current characteristic, in the general case which depends on a local magnetic field and a local temperature. Many investigations are de ...

Chapter 4: Variable Range Hopping Conduction
... In 1968 Mott introduced the concept of a type of hopping conduction called variable range hopping (vrh) [19]. Although Mott’s original manuscript successfully described the empirically observed log σ ∼ T−1/4 dependence, the derivation of this relation proved rather unsatisfactory from a statistical ...
