This new method is compared with the previous one in which bare fibers were etched. With the new process the meniscus formed by the acid along the fiber does not move during etching, leading to a much smoother surface of the tip cone.
WebOptical lithography (also known as photolithography) is a technique based on transferring a pattern from a mask to a surface using a radiation source, such as visible UV light or X … WebWith the nanoisland masks in place, the glass is etched using an inductively coupled plasma reactive-ion-etching (ICP-RIE) system. In this system, an oscillating current in a coil creates a magnetic field that strips molecules in a gas mixture of their electrons, creating a plasma.
WebThe behavior of sputtering yield and the surface roughness of monocrystalline silicon of orientations 100 , 110 , and 111 under the ion-beam bombardment by neutralized Ar ions with energies of 200–1000 eV is studied. The significant dependence (modulation) of sputtering yield on incidence angle due to crystalline structure is observed. It is shown …
