Pengembangan Alat Crystal Growing dengan Metode Bridgman dan Pengujiannya untuk Penumbuhan Single Crystal Sn

Abstract

Pengembangan alat pertumbuhan Crystal Growing berbasis Bridgman telah dilakukan dan diuji melalui penumbuhan Kristal Timah Putih (Sn). Teknik ini menekankan pada metode Bridgman dengan pergerakkan furnice dan sampel, dengan diameter sample sebesar 10mm. Pertumbuhan dilakukan dengan furnice empat zona, dengan gradasi suhu sebesar 11-18̊C/cm. Sample ditumbuhkan dengan kecepatan 3mm/jam, 4 mm/jam, 6mm/jam, 10 mm/jam dan 60 mm/jam. Dan hasil dari penumbuhan Kristal Sn berhasil dilakukan dengan penumbuhan mendekati Kristal tunggal pada pergerakkan sampel dan furnace yang tetap diam. Semakin tinggi kevakuman tabung pyrex dan posisi sampel yang tepat di pertengahan furnice semakin besar peluang mendapatkan Single Crystal.

Research on the development of the Bridgman-based Crystal Growing growth tool has been carried out and tested through the growth of White Tin Crystals (Sn). This technique emphasizes the Bridgman method with furnace and sample movements, with a sample diameter of 10mm. Growth is carried out with a four-zone furnice, with gradations of temperature of 11-18̊C/cm. Samples were grown at speeds of 3mm / hour, 4 mm / hour, 6mm / hour, 10 mm / hour and 60 mm / hour. And the results of the growth of the Sn Crystal were successfully carried out by growing close to a single Crystal in the movement of the sample and furnace which remained stationary. The higher the pyrex tube vacum and the right sample position in the mid furnace, the greater the chance of getting a Single Crystal.
