A scanning tunneling microscope (STM) is a type of scanning probe microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer , then at IBM Zürich , the Nobel Prize in Physics in 1986.
An extension of the multi-tip STM technique is the upgrade to atomic force microscopy (AFM) operation. For applications in nanoelectronics, most of the samples consist of conducting "target" areas at the surface, separated by non-conducting areas.
The STM and STS lack chemical sensitivity. Since the tip-sample bias range in tunneling experiments is limited to /, where is the apparent barrier height, STM and STS only sample valence electron states. Element-specific information is generally impossible to extract from STM and STS experiments, since the chemical bond formation greatly ...
Atomic manipulation is the process of moving single atoms on a substrate using Scanning Tunneling Microscope (STM). The atomic manipulation is a surface science technique usually used to create artificial objects on the substrate made out of atoms and to study electronic behaviour of matter. These objects do not occur in nature and therefore ...
The electrochemical scanning tunneling microscope (EC-STM) is a scanning tunneling microscope that measures the structures of surfaces and electrochemical reactions in solid-liquid interfaces at atomic or molecular scales.

Applications of SP-STM [ edit ] The spin polarized scanning tunneling microscope is a versatile instrument which has gained tremendous attention due to its enhanced surface sensitivity and lateral resolution up to atomic scale, and can be used as an important tool to study ferromagnetic materials, such as dysprosium (Dy), quasi-2D thin films ...
The STM32H7 Series is the first series of STM32 microcontrollers in 40 nm process technology and the first series of ARM Cortex-M7-based microcontrollers which is able to run up to 480 MHz, allowing a performance boost versus previous series of Cortex-M microcontrollers, reaching new performance records of 1027 DMIPS and 2400 CoreMark.
