“…The development of the Callaway model was proposed by Asen-Palmer et al [15]. He successfully modelled the LTC for Ge based on three acoustic modes, where κ is written as a sum of one longitudinal (𝜅 𝐿 ) and two transverse (𝜅 𝑇 ) acoustic phonon branches [16,17],…”

In this study, a simulation of theoretical calculation of Lattice thermal conductivity of Bismuth bulk and nanowires with diameters of 98, 115, and 327 nm in the temperature range of 10 ‒ 300 K and pressure range of 0 ‒ 1.6 GPa was investigated. These calculations were achieved by using the Morelli Callaway model and the Clapeyron equation that both longitudinal and transverse modes are taken into account. Melting temperature, mass density, unit cell volume, mean bond length, lattice parameter, group velocity, and longitudinal and transverse Debye temperature for all transverse and longitudinal modes were calculated for each NW diameter mentioned.

“…Theoretically, various techniques based on density functional theory, the Boltzmann transport equation, the Monte Carlo method, and continuous elasticity theory [27][28][29][30][31] have been used to address different aspects of the thermal transport phenomena in nanostructures. Recently, a substantially accelerated approach was proposed to study the thermal conductivity in bulk and nanoscale materials.…”

“…Although neutron irradiation will always be necessary to test materials for reactor applications, ion beams can provide a lower cost and rapid mechanism for various purposes. Ion irradiation can be any charged particle beam, including electrons, protons or heavier nuclei [1][2][3][4][5][6][7][8][9][10][11]. One of the great advantages of ion irradiation is that it can be conducted for specific energy, dose rate and temperature, leading to a wellcontrolled experiment.…”

The primary aim of this evaluation is to define the radiation level on performing the measurement quantitatively. Three different methods were applied during this process, including simulating by FORTRAN code, measuring by Geiger Muller Counter and calculating with the activity data we had obtained. The simulation provided us an initial value range the radiation would lie in prior to our real operation. It acted as a guide. Measuring the dose rate by handheld Geiger Muller Counter provided the real radiation level during the experiment and can be used to reconfirm the safety condition of the experiment attendant. However, due to the fact that only copper sample from 9 MeV was detected by the Geiger Muller Counter, situation for other energy levels would be predicted by the calculation attempt. We also tried to build a calculation method that could be used more widely.
