A semiconductor crystal of nanometre dimensions with distinctive conductive properties determined by its size.
〔物理〕量子点（一种纳米大小的半导体晶体，按其大小具有明显与众不同的传导特性）
Example sentencesExamples
When hit with light, the quantum dot emits a particular color based on its size.
They repeatedly zapped a 100-nanometer-diameter raised patch of semiconductor called a quantum dot with laser light delivered through a microscopic glass fiber.
Since even a slight change in its properties can radically alter a quantum dot's performance, the control of properties often creates difficulties in device applications.
Chen and Gerion obtained a portion of this protein and attached it to the quantum dot.
In the new study, scientists applied voltage to the electron in a quantum dot, which is a tiny, nanometer-sized semiconductor.
