In subject area: Physics and Astronomy Thermal phenomena refer to the effects of temperature on mechanical responses of microsystems, including thermal strains, coefficient of thermal expansion (CTE) variations, and changes in material parameters like Young’s modulus. AI generated definition based on:...
a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kelvin. Symbol:λork...

Moreover, the direct measurement of temperature as the energy of particles would of course be very difficult to carry out in practice. For these reasons, a conventional but convenient unit of temperature, the degree, is used in physics. It is defined as one-hundredth of the difference between...
The symbol \({{{\mathcal{A}}}\) means the thermodynamic limit of \({{{\mathcal{A}}}_{L}\), while the order of the limit is always in the aforementioned one. We restrict the class of the Hamiltonians, observables, and initial states to simple ones. The Hamiltonian of the system...
Phonon polaritons are promising for infrared applications due to a strong light-matter coupling and subwavelength energy confinement they offer. Yet, the spectral narrowness of the phonon bands and difficulty to tune the phonon polariton properties hinde
Thermal conductivity is defined as the transportation of energy due to the random movement of molecules across the temperature gradient. In other words, it is defined as the measure of a body’s ability to conduct heat. It is represented by the symbol k. ...
It is denoted by the symbol k or λ and the unit is W/m·K. Thermal conductivity of suspensions mainly depends on the particle volume concentrations, particle size and shape, thermal conductivity of particles and fluids, and fluid temperature (Chandrasekar, Suresh, & Senthilkumar, 2012; ...
