概要

• 論文の詳細を見る

• ZnSe bulk single crystals used for the substrate of blue laser device fablication were grown by sublimation method and the quality was evaluated by photolumincscence spectra (PLS). Starting from high purity elements Zn and Se, supplied form company, high purity ZnSe crystals, comparable to the highest one reported so far were grown by this method. In order to obtain the n-type crystals with low resistivity, sublimation grwoth was performed also under controlled vapor pressure of ZnI_2 or ZnCl_2 and it was confirmed that iodine or chlorine is incorporated quantitatively in grown crystal by this method.
