الحقل الكهربائي المتدرج الناتج عن تطعيم نظير الأنديوم 111In في بمورة الياقوت Al2O3 (111In in Al2O3)‎ بتابعية درجة الحرارة

الملخص EN

During past few years physicists were interested in the method of perturbed angular correlation (PAC).

PAC technique has been used to add Isotope of Indium ( 111In) into Sapphire crystal.

PAC is a method which studies the reaction of nuclear torques reaction of active implemented nucleuses sonde with the hyperfine fields that formed in the crystal.

The results showed that the Electrical field gradient (EFG) determined by PAC has formed directly near sonde atoms on crystal lattice.

The gradient of electric field was found due to defects near sonde atoms.

These defects arise from the empty places between atoms inside the lattice.

However, new series of semiconductor depending on PAC techniques were discovered.

These series have big tolerant degrees for high temperatures and high quantum barriers with a wide energy gap.
