在本文中，我们展示了通过退火超薄金膜形成的金纳米岛的横截面透射电子显微镜图像，以正确确定纳米岛的三维形状。研究的样品是沉积在石英上的5和7 nm金膜，并在500和900 °C下退火。金纳米岛的横截面图证实，它们看起来像截短的球体，而不像通常假设的球状体。在不同的样品制备条件下，纳米岛的形状从球形到半球形变化。这些形状与偏振吸收光谱预测的结果一致。
In this paper, we present the cross-sectional transmission electron microscope images of gold nanoislands formed by annealing ultrathin gold films to correctly determine the nanoisland three-dimensional shapes. The samples studied were 5 and 7 nm gold films deposited on quartz and annealed at 500 and 900 °C. The cross-sectional view of the gold nanoislands confirmed that they appear to be like truncated spheres and not like the usually assumed spheroids. The shape of the nanoislands varied from spherical to hemispherical under different sample fabrication conditions. These shapes are consistent with the results predicted by polarized absorption spectroscopy.
