Abstract AR
تم بنجاح ملاحظة تأثير هول في نماذج من الانديوم النتمونايد مع حساب قيم التوصلية، فجوة الطاقة، حركية هول و معامل هول و كانت متطابقة مع النتائج النظرية.
كذلك تم إيجاد تجريبيا قيمة تركيز الحاملات للأنديوم انتمونايد و كانت بحدود (1.6x1016cm-3) مع القيم المحسوبة (1.5x1016cm-3) و نسبة الاختلاف حوالي 6.7 % و هي متوقعة إلى حد ما، و كذلك فإن قيمة زمن التراكب للإلكترون بحدود 45.8x10-8 إضافة إلى ذلك فإن محاولة تم انجازها لإضاءة نموذج الانديوم انتمونايد بمصباح نوع (الدايود الباعث للضوء) كانت بعض النتائج غير متوافقة مع النظرية.
Abstract EN
Various Hall Effects have been successfully observed in samples of n-type indium antimonide with values for conductivity, energy gap, Hall mobility and Hall coefficient all agreeing with theory.
A particular interest in developing a method for obtaining accurate values of carrier concentrations in semiconductor samples has been fulfilled with an experimental result of (1.6 × 1016 cm-3 ± 10.7 %) giving a percentage difference of (6.7 %) to a quoted value of (1.5 × 1016cm-3) at (77K) using an (80mW C.

Although some doubt has been raised as to the validity of effect i.
