    大きなバンドキャップおよび絶縁破壊電界強度の値を有することから次世代パワーデバイス半導体として注目される酸化ガリウムであるが、欠点としてへき開性が高いことが挙げられる。そのため表面加工においてダメージレスな加工法が必要となる。そこで本研究では水素を用いたPCVMによる酸化ガリウムの加工を提案している。結果としてある一定温度を越えると水素ラジカルの脱離によって加工レートが落ちるという結果が得られた。

    From the outbreak of World War II to the present time, people in no fewer than 50 countries have resorted to guerrilla warfare or to other forms of popular armed struggle. The guerrilla liberation struggles were begun in Africa in the 1960's, which provide some of the best examples of national liberation movement. The people of ‘Portuguese’ Guiné took up arms to free their country from colonial domination in 1963 under the leadership of the PAIGC (Partido Africano da Independência da Guiné e Cabo Verde), led by Amilcar Cabral, its founder and secretary-general.
    Amilcar Cabral is gradually gaining recognition as the most original and significant African revolutionary thinker to appear since the death of Franz Fanon and Kwame Nkrumah. This reputation is strengthened by the independence of Guiné-Bissau. Not only did he make notable theoretical contributions to analyzing the reality of his country in the context of national liberation movements, but he also did so in the area of revolutionary practice. The thought of Amilcar Cabral is of primary importance to the people of Africa in the struggles against colonialism and neo-colonialism now going on across the continent. And further, his theories have a great deal of significance for the people and revolutionaries of the three continents. This paper provides a brief assessment of the thought and behavior of Amilcar Cabral. The first part surveys books and articles on the study of Amilcar Cabral. The second part delineates the chronological summary of Amilcar Cabral. The third part traces in outline the thought and activities of Amilcar Cabral.
