Terahertz (THz) radiation is electromagnetic radiation ranging from frequencies of 0.1 THz to 10 THz, with wavelengths between 30μm and 3mm. Reliably detecting this radiation could have numerous valuable applications in ...
Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth. Photonic crystals and metamaterials have proven this by providing ...
As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...
(Phys.org)—Nanoionics is a sub-field of nanotechnology that is concerned with nanoscale phenomena involving migration of ions in solid maters. Thus far, however, the confinement of ionic currents to predefined paths in ...
(Phys.org)—Quantum dots are semiconductor crystals that contain a few hundred atoms constrained into such a small space they're considered zero-dimensional objects, often called "artificial atoms." Researchers have fabricated ...
(PhysOrg.com) -- Finding a simple, scalable way to pattern graphene for future electronics applications is one of the biggest challenges facing graphene researchers. While lithography has been widely used to create graphene ...
(PhysOrg.com) -- By taking advantage of the unique optical properties of nanoscale materials, researchers have designed a lens made of nanowires that can reconfigure its imaging properties without any electronic or mechanical ...
“A nanoimprint method has already been achieved in nanopatterning with a high resolution using negative type photoresist,” Kosei Ueno tells PhysOrg.com. Ueno is a scientist at Hokkaido University in Sapporo, Japan, ...
(PhysOrg.com) -- "Several groups have been using direct laser writing since the end of the 1990s," Michael Thiel tells PhysOrg.com. Thiel is a scientist has been working at the Karlsruhe Institute of Technology (KIT) in Germany. ...
(PhysOrg.com) -- As RFID tags are becoming more widespread for tracking and identifying almost anything, researchers are continuing to develop cheap, ultralow-power memory devices for these applications. In a recent study, ...
Lithography (from Greek λίθος - lithos, 'stone' + γράφειν - graphein, 'to write') is a method for printing using a stone (lithographic limestone) or a metal plate with a completely smooth surface. Invented in 1796 by Bavarian author Alois Senefelder as a cheap method of publishing theatrical works, lithography can be used to print text or artwork onto paper or other suitable material.
