东工大在机械工程、电子电气、材料科学、化学工程、生物科技与信息技术方面尤其强势。这些领域的丰硕科研成果持续推动着日本乃至全球的科技进步。
Materials science is one of its most celebrated strengths. Work on semiconductors, ceramics, alloys and functional polymers has produced highly cited papers and long-term industrial partnerships.
材料科学是它最负盛名的强项之一。围绕半导体、陶瓷、合金与功能高分子的研究产生了大量高被引论文与长期产业合作。
Eg(Si) ≈ 1.1 eV (300 K) | Eg(GaN) ≈ 3.4 eV (300 K) | CO₂ + H₂ → CO + H₂O
For example, silicon has a narrow band gap of about 1.1 eV, while gallium nitride has a wide band gap of about 3.4 eV, which explains why GaN is used in blue LEDs and high-power devices.
例如，硅的带隙约为 1.1 eV，而氮化镓的带隙约为 3.4 eV，这正是 GaN 被用于蓝光 LED 与高功率器件的原因。
