摘要
We have investigated individual bulk-like wires of wurtzite InP using photoluminescence, photoluminescence excitation spectroscopy and transmission electron microscopy. Using two different methods we find that the top of the valence band is split, as expected theoretically. This splitting of the valence band is peculiar to wurtzite InP and does not occur in zinc blende InP. We find the energy difference between the two bands to be 40 meV.
我们用光致发光，光致发光刺激光谱学和传播电子显微镜学调查了 wurtzite InP 的单个像体积的电线。用二个不同方法，我们发现原子价乐队的顶被切开，理论上期望。这切开原子价乐队对 wurtzite InP 古怪并且不发生在锌闪锌矿 InP。我们发现二个乐队之间的精力差别是 40 兆电子伏。
