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.
Mechanism of how density of states influence V-A spectra of tunnel junction. Scanning tunneling spectroscopy is an experimental technique which uses a scanning tunneling microscope (STM) to probe the local density of electronic states (LDOS) and the band gap of surfaces and materials on surfaces at the atomic scale.

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, nano islands and quasi-1D ...
Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope , an instrument for imaging surfaces at the atomic level.
Tunneling applications include the tunnel diode, [5] quantum computing, flash memory, and the scanning tunneling microscope. Tunneling limits the minimum size of devices used in microelectronics because electrons tunnel readily through insulating layers and transistors that are thinner than about 1 nm. [6]
PSTM can be combined with both electron scanning tunneling microscope and AFM in order to simultaneously record optical, conductive, and topological information of a sample. This experimental apparatus, published by Iwata et al., allows the characterization of semiconductors such as photovoltaics, as well as other photo-conductive materials.
Quantum microscopy allows microscopic properties of matter and quantum particles to be measured and imaged. Various types of microscopy use quantum principles. The first microscope to do so was the scanning tunneling microscope, which paved the way for development of the photoionization microscope and the quantum entanglement microscope.
