International Conference on Electronic Properties of Two-Dimensional Systems

Last updated

The International Conference on Electronic Properties of Two-Dimensional Systems (EP2DS), is a biannual event, where over hundred scientists meet for the presentation of new developments on the special field of two-dimensional electron systems in semiconductors. Most transistors in integrated circuits have such a two-dimensional electron system inside, but also the quantum Hall effect was discovered in such a structure.

A semiconductor material has an electrical conductivity value falling between that of a metal, like copper, gold, etc. and an insulator, such as glass. Their resistance decreases as their temperature increases, which is behaviour opposite to that of a metal. Their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure. Where two differently-doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics. Some examples of semiconductors are silicon, germanium, and gallium arsenide. After silicon, gallium arsenide is the second most common semiconductor used in laser diodes, solar cells, microwave frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits.

Transistor semiconductor device used to amplify and switch electronic signals and electrical power

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

The quantum Hall effect is a quantum-mechanical version of the Hall effect, observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall conductance σ undergoes quantum Hall transitions to take on the quantized values

The conference series started 1975 at the Brown University in Providence, Rhode Island, United States. The next in the series will be held July 31-August 4, 2017 at Penn State.

Brown University University in Providence, Rhode Island

Brown University is a private Ivy League research university in Providence, Rhode Island. Founded in 1764 as the College in the English Colony of Rhode Island and Providence Plantations, it is the seventh-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution.

Providence, Rhode Island Capital of Rhode Island

Providence is the capital and most populous city of the U.S. state of Rhode Island and is one of the oldest cities in the United States. It was founded in 1636 by Roger Williams, a Reformed Baptist theologian and religious exile from the Massachusetts Bay Colony. He named the area in honor of "God's merciful Providence" which he believed was responsible for revealing such a haven for him and his followers. The city is situated at the mouth of the Providence River at the head of Narragansett Bay.

Rhode Island State of the United States of America

Rhode Island, officially the State of Rhode Island and Providence Plantations, is a state in the New England region of the United States. It is the smallest state in area, the seventh least populous, the second most densely populated, and it has the longest official name of any state. Rhode Island is bordered by Connecticut to the west, Massachusetts to the north and east, and the Atlantic Ocean to the south via Rhode Island Sound and Block Island Sound. It also shares a small maritime border with New York. Providence is the state capital and most populous city in Rhode Island.

Wrocław Place in Lower Silesian Voivodeship, Poland

Wrocław is a city in western Poland and the largest city in the historical region of Silesia. It lies on the banks of the River Oder in the Silesian Lowlands of Central Europe, roughly 350 kilometres (220 mi) from the Baltic Sea to the north and 40 kilometres (25 mi) from the Sudeten Mountains to the south. The population of Wrocław in 2018 was 639,258, making it the fourth-largest city in Poland and the main city of the Wrocław agglomeration.

Sendai Designated city in Tōhoku, Japan

Sendai is the capital city of Miyagi Prefecture, Japan, the largest city in the Tōhoku region, and the second largest city north of Tokyo. As of 1 August 2017, the city had a population of 1,086,012, and is one of Japan's 20 designated cities. The total area of the city is 786.30 square kilometres (303.59 sq mi).

State College, Pennsylvania Place in Pennsylvania, United States

State College is a home rule municipality in Centre County in the Commonwealth of Pennsylvania. It is the largest designated borough in Pennsylvania. It is the principal borough of the six municipalities that make up the State College area, the largest settlement in Centre County and one of the principal cities of the greater State College-DuBois Combined Statistical Area with a combined population of 236,577 as of the 2010 United States Census. In the 2010 census, the borough population was 42,034 with approximately 105,000 living in the borough plus the surrounding townships often referred to locally as the "Centre Region." Many of these Centre Region communities also carry a "State College, PA" address although are not part of the borough of State College.

Dunkin Donuts Center architectural structure

The Dunkin' Donuts Center is an indoor arena located in downtown Providence, Rhode Island. It was built in 1972, as a home court for the emerging Providence College men's basketball program, due to the high demand for tickets to their games in Alumni Hall, as well as for a home arena for the then-Providence Reds, who played in the nearly 50-year-old Rhode Island Auditorium. Current tenants include the Providence Bruins, of the AHL and the Providence College men's basketball team.
