,The New SI System of Units—The SI of 2018, of a quantum standard of the unit of mass. The practical realization (.) of any unit generally means establishment the value and associated uncertainty of a quantity of the unit of the same kind. . for realization of the units of the SI were prepared by the Consultive Committees of the CIPM. They are presented in Sects. .–..

Scanning Probe Microscopes,f scanning microscopes. In this chapter we discuss also the atomic force microscope (AFM), electrostatic force microscope (EFM), scanning thermal microscope (SThM) and scanning near-field optical microscope (SNOM). We also present a wide range of current and prospective applications of scanning microscopes.

Quantum Hall Effect and the Resistance Standard,nner with a step of ./2. representing the conductance quantum. The quantization of electrical and thermal conductance in nanostructures has been verified experimentally. Conductance quantization in nanostructures is used in the analysis of large-scale integration circuits, as required by the currently used 14 nm technology and future technologies.

Single Electron Tunneling,. We discuss the attempts to construct a direct-current standard with SET junctions and explain why the results are unsatisfactory. We also describe two SET systems of more practical importance: the electron-counting capacitance standard (ECCS) and the Coulomb blockade thermometer (CBT).
