What is a P-N Junction? A p-n junction is a fundamental building block of modern electronics, formed by joining together two types of semiconductor materials: p-type (positive) and n-type (negative).

Last week we covered diodes, specifically thermionic and PN junction diodes. But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be the metal ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

Engineers from North Carolina State University, Adroit Materials and Poland’s Institute of High-Pressure Physics have reduced ...

Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent. Some applications include: rectifiers, signal ORing, transistor turn off ...

We develop a pn junction solar cell using semiconducting BaSi2, which is composed of abundant chemical elements of Si and Ba. Energy conversion efficiencies exceeding 25% will be expected for only a ...

Solids can be categorised into conductors, semiconductors or insulators by their ability to conduct electricity. Electron band theory explains differences in conduction. Semiconductors can be doped ...

This is a preview. Log in through your library . Abstract In this paper we carry out an asymptotic analysis of the system of differential equations describing the transient behavior of a p-n-junction ...

In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline ...
