On the origin of in-gap states in amorphous Ge2Sb2Te5

<p>The localized states in the band gap of amorphous phase change alloys like Ge2Sb2Te5 control the electrical conduction via the Poole-Frenkel mechanism. Understanding...诸如Ge₂Sb₂Te₅的非晶相变合金（amorphous phase change alloys）的禁带（band gap）内的局域态，可通过普尔-弗伦克尔机制（Poole-Frenkel mechanism）调控其导电行为。对……的理解
