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 ...
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.
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.
[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.
The processes that change the internal energy are transfers, into or out of the system, of substance, or of energy, as heat, or by thermodynamic work. [4] These processes are measured by changes in the system's properties, such as temperature, entropy, volume, electric polarization, and molar constitution. The internal energy depends only on ...
