Graphene photodetector enhanced by fractal golden 'snowflake'

(Phys.org)—Researchers have found that a snowflake-like fractal design, in which the same pattern repeats at smaller and smaller scales, can increase graphene's inherently low optical absorption. The results lead to graphene ...

Scientists create first 2-D electride

(Phys.org)—Researchers have brought electrides into the nanoregime by synthesizing the first 2D electride material. Electrides are ionic compounds, which are made of negative and positive ions. But in electrides, the negative ...

Weak-value-based metrology surpasses classical limit

(Phys.org)—When measuring very small physical effects, such as the deflection of a light beam, the very act of measuring can affect the measurement outcome. Now in a new study, physicists have experimentally demonstrated ...

Particles self-assemble into Archimedean tilings

(Phys.org)—For the first time, researchers have simulated particles that can spontaneously self-assemble into networks that form geometrical arrangements called Archimedean tilings. The key to realizing these structures ...

The case for co-decaying dark matter

(Phys.org)—There isn't as much dark matter around today as there used to be. According to one of the most popular models of dark matter, the universe contained much more dark matter early on when the temperature was hotter. ...

Quantum physics offers new way to factor numbers

(Phys.org)—Any number can, in theory, be written as the product of prime numbers. For small numbers, this is easy (for example, the prime factors of 12 are 2, 2, and 3), but for large numbers, prime factorization becomes ...
