The atomistic structure of Czochralski-grown SixGe1-x binary mixed semiconductor was studied experimentally and theoretically. By extended X-ray absorption fine structure (XAFS) studies it was found that bulk SiGe semiconductor is a random mixture and that the Ge-Ge, Ge-Si and Si-Si bond lengths maintain distinctly different lengths and vary in a linear fashion against the alloy composition across the whole composition range 0 < x < 1, in good agreement with expectations derived from the ab-inito electronic structure calculations. The result indicates that SiGe is a suitable model for a disorder mixed material and that the bond lengths and bond angles are distorted with the composition.

Telecommunication service providers are known to provide various benefits for airtime packages. Different packages have been introduced in order to satisfy consumer needs. The nexus between service providers and consumers are guided by terms and conditions. Under Islamic law, any condition stipulated by the parties, which involves riba is rejected ab inito and renders the transaction voidable. Therefore, this article seeks to examine the Airtime Credit Service by service providers such as extra time package known as ‘borrow me credit’ in order to determine whether it is a Shariah-compliant transaction or otherwise. The study adopts doctrinal legal research by using primary and secondary sources of Islamic law such as Qur’an, Sunnah. The study also relies on textbook, journals, and service providers’ websites. The study reveals that the use of the word ‘borrow’ in the package has triggered polemical discourse among the Islamic financial jurists. The study reveals that, although the word ‘borrow’ is used, the intention of service providers is to sell the airtime on credit sale. The article clarifies the juristic discourse of the sale based on Islamic law of contract. It  recommends some clarifications on the form and structure of the sale and concludes that it is allowed for Muslims to buy airtime through the package.
