Micro- and nanoscale heat transfer has drawn the attention of many researchers due to its importance in many advanced manufacturing and materials processing. The traditional phenomenological laws, such as Fourier’s law of heat conduction, are challenged in the microscale regime because (1) the characteristic lengths of the various heat carriers are comparable to each other and to the characteristic length of the system considered, and/or (2) the characteristic times of the various heat carriers are comparable to the characteristic energy excitation time. Thus, microscale heat transfer can be referred to as heat transfer occurring on both the micro-length and micro-time scales. Microscale heat transfer finds applications in thin film (micro- length scale) as well as ultra-short pulsed laser processing (micro- time scale).
