The TEM Observation of an Anomalous Epitaxial Growth in Compound Semiconductors

an investigation about the relationship between insurance lines and economic growth; the case study of iran

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...

Molecular beam epitaxial growth of doped oxide semiconductors.

Molecular beam epitaxy coupled with the use of activated oxygen is shown to be a powerful tool for the growth of well-defined, structurally excellent oxide semiconductor films. The basics of the methodology are discussed. Several case studies are presented to illustrate some of the physical phenomena that can be investigated; these include Cr- and Co-doped TiO(2) anatase, Ti-doped α-Fe(2)O(3) h...

Hydrogen in compound semiconductors

Hydrogen can be inadvertently introduced at any of several steps in the fabrication of optoelectronic devices. The most common consequence of hydrogenation is the passivation of dopant impurities, which leads to a decrease in the electrical conductivity of the material. The most successfully applied experimental technique for directly determining the involvement of hydrogen has been infrared-ab...
