Amorf Dentritik Agatta Quasi Kristallerin Fraktal Büyümesi

Mehmet Bayırlı

Öz


Bu çalışmada katı-katı faz geçişiyle quasi-kristallerin fraktal büyümesi sunulmaktadır. Oldukça yüksek dağılıma sahip rastgele dallanmış kristalleşmiş faz amorf dendritik agatlarda gözlendi. Sırası ile, mangan kristalleri için yoğunluk korelasyon fonksiyonu kritik üssü a ~ 0,308-0,342 ve fraktal boyutu D ~ 1,238-1,626 değerinde yaklaşık hesaplandı. Bu değer difüzyonla sınırlı kümeleşme modeli ile uyum göstermektedir. Fraktal büyümenin gözlendiği diğer sistemlerle karşılaştırılarak oluşum mekanizmaları tartışıldı.
