Unlike "colloidal quantum dots" dispersed in organic solvents through chemical synthesis, "epitaxial quantum dots" fabricated by physicochemical crystal growth methods on single-crystal substrates fixed in a vacuum allow for the precise and controlled fabrication of high-quality single-crystal quantum dots directly on semiconductor wafers. Therefore, they are compatible with existing semiconductor processes, enabling the fabrication of quantum dots within various semiconductor thin-film structures and their application to diverse optoelectronic devices.

Part 4: Development of Films Emitting Primary Colors Using Wavelength Control of Light in Silicon Quantum Dots

【Lecture Summary】

Currently, the quantum dots (QDs) in practical use are mainly In-based, and research is also centered on perovskite (lead-containing), In-based, and Cd-based QDs. These are applied in TVs, and broad applications are expected in VR/AR, sensors, solar cells, and pharmaceuticals in the future.

Globally, however, there is a strong demand for next-generation QDs that meet three criteria: (1) general-purpose raw materials, (2) non-toxic, and (3) heavy metal-free. Silicon is one of the leading candidates. It does not contain heavy metals, and its potential to utilize discarded solar panels as a resource in the future is also attractive.

Previously, the luminous efficiency in the near-infrared region was low, around only 0.01%, making practical application seem difficult. However, the situation has changed dramatically with miniaturization (quantum dot formation), with efficiency improving up to 90%, and full-color emission is also becoming possible.

This seminar will clearly explain the manufacturing methods, structure, properties, and LEDs of silicon quantum dots (SiQDs). It will also cover research results on SiQD films and bio-applications, including SiQD LEDs for which four world records have been established.
