ng of the tips is done under the control of an optical microscope or an SEM in vacuum. The heart of this STM is a new type of piezoelectric coarse approach called Koala Drive which can have a diameter greater than 2.5 mm and a length smaller than 10 mm.

Christa Kleindienst-Cachay,Steffen Bahlkedevices. Local electrical contacts, namely nanoelectrodes, are often fabricated by using top-down lithography and chemical etching techniques. These processes however lack atomic precision and introduce the possibility of contamination. Here, we review recent reports on the application of a field-inMalleable 发表于 2025-3-26 09:25:06

Kerstin Pößiger,Söhnke Vosgerau with metal-coated carbon nanotube (CNT) tips. We first present our custom-made apparatus (with UNISOKU Co.) as well as CNT tips, and then some case studies with two different samples, Co-silicide nanowires self-assembled on Si(110) surface and Cu nanowires made by damascene processes used in LSI in
