Trap-Dominated Electrical and Optical Effects in Crystalline Borontion in the near infrared after illumination with visible light. Since boron is opaque for wavelengths shorter than 0.8 . , the photoexcitation must occur in a thin surface layer of the crystal. Typical experiments are performed in three phases, namely, (1) photoexcitation, (2) observation of fast a

Carbon and silicon, in contrast to germanium, cause electron paramagnetic resonance with a . value about 2. 003. A similar resonance is found in B.C.; in both cases, it is probably related to unsaturated bonds of a radical type induced by the foreign atoms.

Prozesse als Abläufe verteilter Systeme The main impurity in our boron is carbon (30–50 ppm). Because of the unfavorable distribution coefficient for carbon in boron (approx. 4), removal by zone-refining is very time-consuming. A coulometric, method to determine carbon in boron is discussed.
