Junction box
A junction box, also known as a junction block, is an enclosure in an electrical wiring system that houses and protects connections between conductors, governed by codes such as the NEC.
Junction depth
Junction depth (xj) is the depth below a semiconductor surface at which an implanted dopant concentration equals the background doping, marking the metallurgical p-n junction.
Junction temperature
Junction temperature is the temperature of the active region of a semiconductor laser, LED, or power device, which sets its threshold, wavelength, efficiency, and lifetime, and always runs above the case or heatsink temperature.
Junction temperature estimation
Junction temperature estimation is the set of electrical, optical, and model-based methods for determining a semiconductor junction's temperature inside a packaged device, used for reliability testing and thermal management.
Junction Tree VAE
The Junction Tree Variational Autoencoder (JT-VAE or JTVAE) is a generative model introduced at MIT in 2018 that produces chemically valid molecules by first generating a scaffold of substructures, then assembling them.
Junction working (manual telephony)
Junction working was the method by which manually operated telephone exchanges were interconnected: a call was extended over a dedicated junction circuit and completed by operators at the distant board.
Junctionless transistor
A junctionless transistor is a field-effect transistor with no p-n junction; the first working device was a silicon nanowire built at the Tyndall National Institute in 2010.
