Researchers have developed a technology to produce environmentally friendly water-borne semiconductor inks using surfactant. The result is expected to be applied to various electronic devices with a semiconductor surface control technique.
These optical devices, made of graphene and a punctured gold surface, could become optical components for advanced applications, such as amplitude tunable lenses, lasers (i.e. vortex phase plates), and dynamic holography.
Carbon nanotubes (CNTs) either cannot be combined adequately with other materials, or if they can be combined, they then lose their beneficial properties. Scientists have now developed an alternative method, with which CNTs can be combined with other materials, so that they retain their characteristic properties.
