Detailed explanation-1: -Gold that’s just two atoms thick has been created in a lab by British scientists. The “world’s thinnest gold” is one million times thinner than a fingernail – and is so thin, it’s technically regarded as “two dimensional.”
Detailed explanation-2: -It’s only 0.47 nanometers thick, which is one million times thinner than a human finger nail.
Detailed explanation-3: -Researchers from Tel Aviv University have engineered the world’s tiniest technology, with a thickness of only two atoms. According to the researchers, the new technology proposes a way for storing electric information in the thinnest unit known to science, in one of the most stable and inert materials in nature.
Detailed explanation-4: -That accolade goes to graphene, a form of carbon: sheets of it are only one atom thick. A very familiar form of carbon is graphite, as used in pencils.
Detailed explanation-5: -Because it is unusually ductile, gold can be made into a foil that is only 0.00004 cm thick.
