Beroende av koncentrationen av arsenik-antisitedefekter och tvådimensionellt tillväxtläge på LT GaAs-tillväxtförhållanden Vi undersökte beroendet av arsenikantisitedefektkoncentration och av epitaxiell tjocklek (tepi), över vilken en övergång till tredimensionell tillväxt uppträder, på tillväxtförhållandena för [ ...]
The impurity elements in crystalline silicon materials mainly include non-metallic impurities such as carbon, oxygen, boron, and phosphorus, and metal impurity such as iron, aluminum, copper, nickel, and titanium. Metal impurities generally exist in interstitial states, substitution states, complexes or precipitations in crystalline silicon, [...]
