ガリウム砒素半導体は、高速トランジスタに使われている。
Gallium arsenide semiconductors are used in high-speed transistors.
Standard technical spelling using the kanji 砒素 for arsenic.
Mixed kana-kanji spelling; 砒 is replaced by hiragana ひ, which may be used when the kanji is unavailable or for readability.
Compound of ガリウム (gariumu, 'gallium'), 砒素 (hiso, 'arsenic'), and 半導体 (handōtai, 'semiconductor'). The term is a direct technical translation of the English 'gallium arsenide semiconductor'.
