Tunnel injection. Tunnel injection is a field electron emission effect; specifically a quantum process called Fowler–Nordheim tunneling, whereby charge carriers are injected to an electric conductor through a thin layer of an electric insulator. It is used to program NAND flash memory. The process used for erasing is called tunnel release.
The so-called standard Fowler–Nordheim-type equation, originally developed by Murphy and Good, [72] and much used in past literature, is obtained by putting λ Z →t F −2, P F →1, →v F, where v F is v(f), where f is the value of f h obtained by putting h=φ, and t F is a related parameter (of value close to unity).
Radioactive decay is the process of emission of particles and energy from the unstable nucleus of an atom to form a stable product. This is done via the tunnelling of a particle out of the nucleus (an electron tunneling into the nucleus is electron capture). This was the first application of quantum tunnelling.
The B2FH paper[1] was a landmark scientific paper on the origin of the chemical elements. The paper's title is Synthesis of the Elements in Stars, but it became known as B 2 FH from the initials of its authors: Margaret Burbidge, Geoffrey Burbidge, William A. Fowler, and Fred Hoyle. It was written from 1955 to 1956 at the University of ...
The term “hot carrier injection” usually refers to the effect in MOSFETs, where a carrier is injected from the conducting channel in the silicon substrate to the gate dielectric, which usually is made of silicon dioxide (SiO 2). To become “hot” and enter the conduction band of SiO 2, an electron must gain a kinetic energy of ~3.2 eV.
Nitrogen washout. Nitrogen washout. Purpose. detects/ measures dead space in lungs. Nitrogen washout (or Fowler's method) is a test for measuring anatomic dead space in the lung during a respiratory cycle, as well as some parameters related to the closure of airways.
