International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015 The behavior of iron, iron‐boron (FeB) pairs, and iron‐boron‐phosphorus (FeB‐P) complexes has been studied in B‐doped Czochralski silicon with phosphorus (P) compensation and compared with that in uncompensated material. The interstitial iron concentration has been measured at temperatures from 50 to 270°C.

Determination of Gallium Concentration in Silicon from Low‐Temperature Photoluminescence Analysis
Solar RRL, Volume 8, Issue 4, February 2024.A simple method for determining the gallium concentration in silicon for solar photovoltaic applications is presented. It relies on the intensity ratio for bound exciton to the free exciton peaks from photoluminescence measurements at 10 K. The empirical relation describing the calibration curve is deduced, and the effect of temperature and power on ...

Modelling of the Czochralski flow
Abstract and Applied Analysis, Volume 3, Issue 1-2, Page 1-40, 1998., 1998 The Czochralski method of the industrial production of a silicon single crystal consists of pulling up the single crystal from the silicon melt. The flow of the melt during the production is called the Czochralski flow. The mathematical description of the flow consists of a coupled system of six P.D.E.

Occupation as social practice and ambiguous space: the lives of Ludwik Hirszfeld and Jan Czochralski in Warsaw 1939-1944 [PDF]
, 2022 This article evaluates the situation of two renowned scientists in Poland, namely the microbiologist and serologist Ludwik Hirszfeld (1884–1954), and the metallurgist Jan Czochralski (1885–1953), during the time of the German occupation from 1939–45. Both scientists strove to continue their scientific work even under the conditions of occupation but ...
