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.

İnce Cu2ZnSnS4 (CZTS) filmin RBS spektrumundan enerji kaybı analizi

Öz

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.
