111Glass transition — The liquid glass transition (or glass transition for short) is the reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle state into a molten or rubber like state …
112Caesium — xenon ← caesium → barium Rb ↑ Cs ↓ Fr …
113Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
114MOSFET — Two power MOSFETs in the surface mount package D2PAK. Operating as switches, each of these components can sustain a blocking voltage of 120 volts in the OFF state, and can conduct a continuous current of 30 amperes in the ON state, dissipating up …
115Electrostatics — For a less technical introduction, see Static electricity. Electromagnetism …
116Scanning tunneling spectroscopy — (STS) is a powerful experimental technique in scanning tunneling microscopy (STM) that uses a scanning tunneling microscope (STM) to probe the local density of electronic states (LDOS) and band gap of surfaces and materials on surfaces at the… …
117Coulomb gap — First introduced by M. Pollak [1], the Coulomb gap is a soft gap in the Single Particle Density of States (DOS) of a system of interacting localized electrons. Due to the long range Coulomb interactions, the single particle DOS vanishes at the… …
118Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
119photoelectric effect — Physics. the phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface. Also called photoemission. [1890 95] * * *… …
120high-pressure phenomena — ▪ physics Introduction changes in physical, chemical, and structural characteristics that matter undergoes when subjected to high pressure. pressure thus serves as a versatile tool in materials research, and it is especially important in… …
