Lefatše le Hlollang la Molecular Beam Epitaxy MBE: R&D le Tlhahiso ea likarolo tsa Vacuum Chamber

Rea u amohela lefatšeng le letle la lisebelisoa tsa molek'hule tsa epitaxy MBE!Sesebelisoa sena sa mohlolo se ka holisa lisebelisoa tse ngata tsa boleng bo holimo tsa nano-scale semiconductor, tse phethang karolo ea bohlokoa ho nts'etsopele ea masimo a kajeno a saense le thekenoloji.Theknoloji ea MBE e hloka ho etsoa sebakeng sa vacuum, kahoo likarolo tsa bohlokoa tsa kamore ea vacuum li ile tsa hlaha.
