Some metallic nanoparticles<\/a> can absorb light and generate both positive and negative electrical charges. If these charges develop in light absorption they are referred to as \u2018hot\u2019, the positive charges of which are known as \u2018electron holes\u2019 because they are missing an electron in the valence band.<\/p>\n The well-studied phenomenon of hot electrons can accumulate in semiconductors, extending their life and enabling them to be used in photocatalysts, solar cells, and photosensors.<\/p>\n The research team from Uppsala University<\/a> published its \u00a0findings in the journal Nature Materials<\/em><\/a>. The paper suggests that the team collected more than 80% of the hot holes in a semiconductor, which is three times as many as expected.<\/p>\n
