项目摘要

酸化物半導体MgZnO/ZnOヘテロ界面におけるスピン軌道相互作用の電界制御を実現することで，分極不整合によって生じる高品位の2次元電子系を活用したスピン共鳴トランジスタの構築を目指すことが本研究の目的である．2014年度は高品位の酸化物2次元電子系を作製する準備段階として，まず，酸化物半導体薄膜の成長技術の確立に取り組んだ．現有のパルスレーザー堆積装置，X線回折装置及び原子間力顕微鏡を用いて，酸化物薄膜の成長とその評価を行った．それに加えて，電気二重層トランジスタを使った電界効果デバイスの作製に取り組んだ．その結果，平均面粗さ1nm以下の平坦な薄膜を得ることができた．今後，ヘテロ界面を設計し，2次元電子系の量子輸送を測定する予定である．また，電気二重層トランジスタのHall効果測定から，印加電圧に対してキャリア濃度の変調ができており，酸化物薄膜が形成する2次元電子系と組み合わせたスピン軌道相互作用の電界制御が期待できる．

The acidified semi-solid MgZnO/ZnO interface leads to the interaction between the two components in the electrical industry, and it is highly unintegrated to produce high-grade high-grade secondary electronics. the purpose of this study is to achieve the purpose of this study. The growth technology of acidified semi-bulk thin films ensures that the components are available. There are some equipment for the growth of acidified thin films, such as X-ray refolding devices, X-ray back-folding devices and atomic force micro-sensors. The growth of acidified thin films has led to the growth of high-temperature carbon thin films. The electronic duplex filter makes it possible for the electronic industry to obtain reliable data acquisition results. The average surface thickness of the flat thin film below 1nm is very high. From now on, the interface is set up, the two-dimensional electronic system is used to determine the temperature of the quantum device, the output of the two-dimensional electronic system is measured, the Hall is measured, and the temperature of the Inca electronic system is measured. Acidified thin films are formed into two-dimensional electronic systems, and the interaction between two-dimensional electronic systems is expected to be controlled by the electrical industry.
