Elusive Polarons Discovered in Two-Dimensional Semiconductor

■ Natural Sciences / Elusive Polarons Discovered in Two-Dimensional Semiconductor Electrons moving inside a solid and surrounded by a moving charge distortion, known as Holstein polarons, have been discovered in the MoS2 two-dimensional semiconductor. An electron passing through a solid can affect the atoms of that material by creating a surrounding area of distorted charge. From another perspective, the electron can be seen as moving while carrying this surrounding distortion; this kind of electron is called a “polaron.” There are two types of polaron: Fröhlich and Holstein. In a study recently published in the scientific journal Nature Materials, scientists at Yonsei University led by Prof. … Continue reading Elusive Polarons Discovered in Two-Dimensional SemiconductorRead More →
