Softcover. Etat : Very Good. In The Physical Review, volume 87(5), September 1, 1952. This is pp. 835-842. Entire issue in blue paper wraps; very good with solid binding and slight wear to top of fore-edge and corners. This paper, which has been cited over 2500 times (Science Citation Index), was the first model of electron-hole recombination in a highly pure semiconductor, now known as Shockley-Read-Hall (SRH) recombination and of importance in semiconductors and solar technology. Issue also contains papers by Abraham Pais, Vera Kistiakowsky and others. * 003421.…

Read, Jr. "Statistics of the Recombinations of Holes and Electrons", in Physical Review, vol. 87, Issue 5, pp. 835-842, offered in the issue of pp 685-913. Original wrappers. Very good, solid copy, with the "AW" iin pen at upper right cover corner. Nice clean spine. An important paper cited 3000+times. "The statistics of the recombination of holes and electrons in semiconductors is analyzed on the basis of a model in which the recombination occurs through the mechanism of trapping. A trap is assumed to have an energy level in the energy gap so that its charge may have either of two values differing by one electronic charge. The dependence of lifetime of injected carriers upon initial conductivity and upon injected carrier density is discussed."--Smithsonian/NASA Astrophysics Data Center. …

1st Edition. BOUND FULL VOLUME FIRST EDITION OF THE FIRST MODEL OF ELECTRON-HOLE RECOMBINATION IN A HIGHLY PURE SEMICONDUCTOR. Cited over 2500 since publication, this model is now known as the Shockley-Read-Hall (SRH) recombination and is of import to solar and semiconductor technology. "Any electron which exists in the conduction band is in a meta-stable state and will eventually stabilize to a lower energy position in the valence band. When this occurs, it must move into an empty valence band state. Therefore, when the electron stabilizes back down into the valence band, it also effectively removes a hole. This process is called recombination" (Honsberg & Bowden, Types of Recombination). The model Shockley and Read put forth in this paper is essentially recombination through defects; in other words, recombination does not happen in a pure material. The steps involved in SRH are two-fold: (1) "An electron (or hole) is trapped by an energy state in the forbidden region which is introduced through defects in the crystal lattice. These defects can either be unintentionally introduced or deliberately added to the material, for example in doping the material; and (2) If a hole (or an electron) moves up to the same energy state before the electron is thermally re-emitted into the conduction band, then it recombines. "The rate at which a carrier moves into the energy level in the forbidden gap depends on the distance of the introduced energy level from either of the band edges. Therefore, if an energy is introduced close to either band edge, recombination is less likely as the electron is likely to be re-emitted to the conduction band edge rather than recombine with a hole which moves into the same energy state from the valence band. For this reason, energy levels near mid-gap are very effective for recombination" (ibid). ALSO INCLUDED IN THIS ISSUE: PFIRST EDITION IN ORIGINAL WRAPS OF DONALD GLASER'S NOBEL PRIZE WINNING INVENTION OF THE BUBBLE CHAMBER USED IN SUB ATOMIC PARTICLE PHYSICS. Glaser was an American physicist and neurobiologist who, inspired by the bubbles in a glass of beer, invented a vessel that, when filled with a superheated transparent liquid like liquid hydrogen, is able to detect electrically charged particles moving through it. Glaser's bubble chamber made it possible for scientists "to observe the paths and lifetimes of particles" in sub atomic particle physics (Wikipedia). Bubble chambers are created by filling "a large cylinder with a liquid heated to just below its boiling point. As particles enter the chamber, a piston suddenly decreases its pressure, and the liquid enters into a superheated, metastable phase. Charged particles create an ionization track, around which the liquid vaporizes, forming microscopic bubbles. Bubble density around a track is proportional to a particle's energy loss. Bubbles grow in size as the chamber expands, until they are large enough to be seen or photographed" (Wikipedia). Glaser was awarded the Nobel Prize in 1960 for his invention.
