İnce Cu2ZnSnS4 (CZTS) filmin RBS spektrumundan enerji kaybı analizi

Abstract

Bu çalışmanın amacı, CZTS ince filmlerinin enerji kaybını belirlemek için mevcut literatüre alternatif bir yöntem sunmaktır. Bu amaçla, ince CZTS film yapıları ilkönce sol-gel yöntemiyle üretildi ve daha sonra bu yapı bir mikroışın çemberinde 3.034 MeV protonlarla ışınlanarak RBS detektörüyle RBS spektrumu alındı. SIMNRA programıyla fit edilen bu spektruma enerji kalibrasyonu uygulandı. Üretilen ince filmlerin RBS spektrumunda, ilgili piklerin konum ve enerji genişliği analizinden enerji kaybı hesaplaması için bir yöntem kullanıldı ve belirli yaklaşımlar yaparak CZTS ince filmin durdurma gücünden bir polinom fit elde edildi. Ayrıca, durdurma gücü için önceki çalışmalarda kullandığımız etkin yük yaklaşımı atomik doğal orbitaller ile kullanıldı ve sonuçların belirli hata oranlarında birbirine yakın oldukları bulundu. Bu çalışmadan elde edilen veriler maddeyle radyasyonun etkileşmesi üzerine yapılacak çalışmalara ilham verecektir.

Energy loss analysis from RBS spectrum of thin Cu2ZnSnS4 (CZTS) film

Abstract

The goal of this work is to offer an alternative method to the available literature on determining the energy loss of CZTS thin films. For this purpose, thin CZTS film structures were first produced by sol-gel method and then the RBS spectrum was received with RBS detector irradiating this structure with 3.034 MeV proton beams in a microbeam chamber. The energy calibration was implemented to this spectrum, where the it was fitted with SIMNRA program. In the RBS spectrum of the thin film generated, a method for the calculation of energy loss was used for the position and energy width analysis of the corresponding peaks and a polynomial fit was obtained from the stopping power of the CZTS thin film by making certain approaches. Also, the effective charge approach that we used in our previous studies for the stopping power was employed with atomic natural orbitals and it was founded that the results were close to each other at certain error rates.  The data obtained from this study will inspire the future studies on the interaction of radiation with matter.
