Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

and holes (p-type) cancel each other and form a "depletion zone" that acts as a non-conductive barrier. The PN junction is one of the primary building blocks of semiconductors. A diode (one way ...

and in the p-type layer, there is an excess of positively charged holes (which are vacancies due to the lack of valence electrons). Near the junction of the two layers, the electrons on one side of ...

The sandwich transistor was William Shockley's brainchild. It's also called the junction transistor. While the rest of the lab was busy researching Bardeen and Brattain's point-contact transistor ...

Magnetic Tunnel Junctions are a type of tunnel junction where the electrodes are ferromagnetic materials, such as iron, cobalt, or their alloys. The tunneling current in an MTJ depends on the relative ...
