Molecular transistor, AFM
Molecular transistor. Coloured atomic force micro- graph (AFM) of a transistor on the molecule scale. It consists of electrodes (yellow) created by electron beam lithography (EBL) linked with a carbon nanotube. EBL uses an electron beam to etch structures onto a surface. Transistors control current in electronic circuits. Their miniaturis- ation has led to faster and faster computers. Atomic force microscopy is a technique used for studying surfaces at an atomic level. A thin probe is moved over the surface, and its movements as it follows the contours are used to create an image.

EDITORS COMMENTS
This print showcases a molecular transistor, captured in stunning detail through the use of atomic force microscopy (AFM). The image reveals a colored AFM graph, highlighting the intricate structure of this technological marvel. At its core, the transistor consists of electrodes - depicted in yellow - meticulously created using electron beam lithography (EBL) and connected with a carbon nanotube. Transistors play a pivotal role in controlling current within electronic circuits, enabling the functionality of various devices we rely on daily. Their miniaturization has been instrumental in propelling computer technology forward at an unprecedented pace. This remarkable progress is beautifully exemplified by this molecular-scale transistor. The AFM technique employed to capture this image allows scientists to study surfaces at an atomic level. By delicately maneuvering a thin probe over the surface and mapping its movements as it traces every contour, researchers can generate highly detailed images like this one. With a magnification factor of x35,000 at 6x6cm size, viewers are granted access to an extraordinary world where electrons dance across circuitry on an unimaginably small scale. This photograph not only showcases cutting-edge advancements in electronics but also serves as a testament to the incredible potential that lies within nanotechnology and integrated circuits.
