The XRD validates the cubic spinel-type arrangement within the Fd3m space group and reveals the crystalline sizes for x = 0.4 and 0.6 to be 45 and 39 nm, respectively. Furthermore, for the surface morphology of the sample and elemental stoichiometry, the SEM and EDS were studied. The UV–Vis spectroscopy and FTIR studies reveal the alternation of structure and modifications in the optical band gap of x = 0.4 and 0.6 as 2.0 and 2.18 eV, respectively, resulting from the incorporation of Zn ions. The XPS analysis was carried out to confirm the chemical bonding environment of elements and binding energy. The magnetization behavior at room temperature demonstrated a decrease in the magnetic saturation (Ms) of Ni ferrite with an increase in Zn content. The electrical characteristics indicated semiconductor-like behavior for both samples.

The main focus is on understanding the impact of self-heating on the alteration of mobility of electrons profile. This paper introduces a model that takes into account the influence on temperature and doping on the electron mobility in β-Ga₂O₃. Furthermore, it offers estimations for the conductivity of heat of β-Ga₂O₃, considering the influence of temperature and crystalline orientation. Furthermore, we showcase a practical example of modulation-doped β-(Al_xGa_1-x)₂O₃/Ga₂O₃ using a tri-metal FET where the energy level difference between the conduction bands and the presence of undesired channels in the barrier layer determines the maximum sheet carrier density in this structure. These channels enable the transfer of electrons from both the bottom and upper portions of the β-Ga₂O₃ quantum well. Using modulation doping, the proposed structure exhibited an ultimate current drain of 250 mA/m, a peak conductivity of 40 ms/m, and a potential of 10.0 V at ambient temperature. The electrical characteristics of the TMG device were evaluated by comparing it to the double-metal gate (DMG) device using the Atlas Silvaco TCAD simulation for analysis of performance. The results indicate that, the suggested device exhibits greater efficiency in terms of conductivity, current gain cut-off frequency, and energy gain cut-off frequency as compared to DMG transistors. The measured electric field in this example is a consequence of using a Tri-Metal Gate architecture (TMG) to regulate the channel.
