  2. Intrinsic and extrinsic properties - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_and_extrinsic...

    In electronics and optics, intrinsic properties of devices (or systems of devices) are generally those that are free from the influence of various types of non-essential defects. [3] Such defects may arise as a consequence of design imperfections, manufacturing errors, or operational extremes and can produce distinctive and often undesirable ...

    en.wikipedia.org/wiki/Permeability_(Materials...

    Permeability, or intrinsic permeability, (k, unit: m 2) is a part of this, and is a specific property characteristic of the solid skeleton and the microstructure of the porous medium itself, independently of the nature and properties of the fluid flowing through the pores of the medium.

  6. Molar absorption coefficient - Wikipedia

    en.wikipedia.org/wiki/Molar_absorption_coefficient

    It is an intrinsic property of the species. The SI unit of molar absorption coefficient is the square metre per mole ( m 2 /mol ), but in practice, quantities are usually expressed in terms of M −1 ⋅cm −1 or L⋅mol −1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol ).

  7. Surface states - Wikipedia

    en.wikipedia.org/wiki/Surface_states

    A simple model for the derivation of the basic properties of states at a metal surface is a semi-infinite periodic chain of identical atoms. [1] In this model, the termination of the chain represents the surface, where the potential attains the value V 0 of the vacuum in the form of a step function , figure 1 .

  8. Physical property - Wikipedia

    en.wikipedia.org/wiki/Physical_property

    A physical property is any property of a physical system that is measurable. [1] The changes in the physical properties of a system can be used to describe its changes between momentary states. A quantifiable physical property is called physical quantity. Measurable physical quantities are often referred to as observables.

  9. Intensive and extensive properties - Wikipedia

    en.wikipedia.org/wiki/Intensive_and_extensive...

    [1] [2] According to International Union of Pure and Applied Chemistry (IUPAC), an intensive property or intensive quantity is one whose magnitude is independent of the size of the system. [3] An intensive property is not necessarily homogeneously distributed in space; it can vary from place to place in a body of matter and radiation.
