description Daniel C. Tsui Overview

Daniel C. Tsui is a physicist specializing in condensed matter physics and quantum phenomena. He gained international recognition for his pivotal role in experimentally demonstrating the fractional quantum Hall effect, a discovery that earned him a share of the 1998 Nobel Prize in Physics. His work has significantly advanced our understanding of electron behavior at low temperatures and remains crucial for researchers exploring topological materials and novel electronic devices.

Tsui’s expertise is primarily utilized by academics and scientists investigating fundamental physics within these areas.

help Daniel C. Tsui FAQ

What discovery earned Daniel C. Tsui the Nobel Prize?

Tsui shared the 1998 Nobel Prize in Physics with Horst Störmer and Robert Laughlin for the discovery and explanation of the fractional quantum Hall effect. In 1982, Tsui and Störmer observed that electrons confined to a two-dimensional layer at extremely low temperatures and high magnetic fields behaved as though they carried fractional electric charges.

Where did Daniel C. Tsui make his Nobel Prize discovery?

Tsui and Störmer conducted their pivotal experiments at Bell Laboratories in Murray Hill, New Jersey, using gallium arsenide semiconductor heterostructures built by molecular beam epitaxy. Robert Laughlin, then at Lawrence Livermore National Laboratory, provided the theoretical explanation that the electrons had formed a new type of quantum fluid.

What is the significance of the fractional quantum Hall effect?

Before this discovery, it was believed that electric charge could only come in whole units of the electron charge. The fractional quantum Hall effect demonstrated that under extreme conditions, collective electron behavior produces quasi-particles carrying exactly one-third of an electron charge, revealing an entirely new state of matter.

Where was Daniel C. Tsui born and educated?

Tsui was born in 1939 in Henan Province, China, and came to the United States to attend Augustana College in Rock Island, Illinois. He earned his PhD in physics from the University of Chicago in 1967 under the supervision of Robert Merrifield before joining Bell Labs.
