Princeton University is a private Ivy League research university in Princeton, New Jersey. Founded in 1746 in Elizabeth as the College of New Jersey, Princeton is the fourth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. The institution moved to Newark in 1747, then to the current site nine years later, and renamed itself Princeton University in 1896.

Ultra-pure semiconductor opens new frontier in the study of electrons

“Princeton researchers have created the world’s purest sample of gallium arsenide, a semiconductor used in devices that power such technologies as cell phones and satellites. The team baked their material down to one impurity for every 10 billion atoms …

Unmasking the magic of superconductivity in twisted graphene

“The discovery in 2018 of superconductivity in two single-atom-thick layers of graphene stacked at a precise angle of 1.1 degrees (called ‘magic’-angle twisted bilayer graphene) came as a big surprise to the scientific community. Since the discovery, physicists …

Researchers invent world’s smallest biomechanical linkage

“Researchers at Princeton University have built the world’s smallest mechanically interlocked biological structure, a deceptively simple two-ring chain made from tiny strands of amino acids called peptides. In a paper published August 23 in Nature Chemistry, the team detailed …

New evidence for electron’s dual nature found in a quantum spin liquid

“A new discovery led by Princeton University researchers could upend our understanding of how electrons behave under extreme conditions due to the laws of quantum physics. The finding provides experimental evidence that this familiar building block of matter often behaves …

Materials advances are key to development of quantum hardware

“A new study outlines the need for materials advances in the hardware that goes into making quantum computers if these futuristic devices are to surpass the abilities of the computers we use today. The study(link is external), published in …

Low-cost solar-powered water filter removes lead, other contaminants

“A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid. The device resembles a large sponge that soaks up water but leaves contaminants – like lead, oil and pathogens …

Discovery of quantum behavior in insulators suggests possible new particle

“In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed in metals rather than insulators, and its discovery offers …

Super surfaces use terahertz waves to help bounce wireless communication into the next generation

“Assembling tiny chips into unique programmable surfaces, Princeton researchers have created a key component toward unlocking a communications band that promises to dramatically increase the amount of data wireless systems can transmit. The programmable surface, called a metasurface, allows engineers …

Strange quasi-particles reveal new magnetic behavior, verify nearly century-old prediction

“Princeton researchers have confirmed a theory first put forward in 1929 by the Nobel laureate Felix Bloch, who theorized that certain kinds of materials, when drawn down to a very low electron density, would spontaneously magnetize. In the study, published …

Controlling heat opens door for next-generation lighting and displays in perovskite LEDs

“Light-emitting diodes, or LEDs, are nearly ubiquitous in modern life, providing the brightness in phone displays, televisions, and lights. A new form of LEDs, made of a class of materials called halide perovskites, promises higher color quality and ease of …
