1.08 Extrinsic semiconductor. To produce extrinsic semiconductor material specific amounts of impurity are added to the pure intrinsic semiconductor. This process is called doping and the impurity atoms are called donor atoms.There are two types of extrinsic semiconductor which are manufactured, P type semiconductor and N type semiconductor.his process is called doping and the impurity atoms are called donor atoms.

decontamination process using spores of Bacillus stearothermophilus has gained widespread acceptance. Usually, commercially available Biological Indicators (BIs) with a specified resistance to H 2 O 2 are challenged to qualify the process. The question arises whether the resistance of test spores is dependant on the type of carrier material and whether the resistance is representative for the system under test. The objective of the study is to quantify the effect of different carrier materials on the resistance of spores of Bacil- lus stearothermophilus to HO. Materials from which isolators were built, as well as those used in disposables during
