However, achieving large-area, high-quality single-crystal InP films on silicon remains a major challenge. In this work, 4-inch, 200 nm-thick single-crystal InP thin films were successfully transferred onto silicon substrates using ion-cutting of an InP/InGaAs epitaxial structure. To address thermal stress issues during the ion-cutting process for large-area heterogeneous integration wafers, finite element simulations were conducted to analyze thermal stress distributions under different bonding and annealing temperatures. The simulation results revealed abrupt thermal stress concentrations at the edges of the InP/Si bonding pairs, which could be mitigated by bonding at an elevated temperature of 55 °C. The InP/InGaAs epitaxial structure effectively reduced the residual H-ion concentration of the InP film after annealing, with defects localized in the epitaxial InGaAs layer. Following the selective etching of the InGaAs layer, a high-quality 4-inch InP thin film was obtained, exhibiting a surface roughness of 0.347 nm, a full width at half maximum (FWHM) of 212.4 arcsec for the X-ray rocking curve, and a thickness uniformity of 98 %.

Through numerical simulation, the regulation mechanism of slot structures on arc motion and erosion distribution is revealed. Experimental results demonstrate that spiral-type TMF contacts reduce arc constriction through arc slot crossing, yet suffer aggravated local erosion at slot edges due to arc stagnation. Cup-shaped TMF contacts exhibit higher arc constriction with more centralized erosion distribution. Thermal process simulations further indicate that slot structures disperse arc energy across slot regions, delaying the formation of high-temperature zones on opposite contact surfaces and causing arc stagnation. The introduction of preheating conditions enables earlier formation of continuous high-temperature zones on anode surfaces. The stagnation time decreased to 1.0 ms with a simultaneous rise in motion speed to 173.4 m/s, ultimately alleviating slot edge erosion.
