الوصف: | The scalable synthesis of strong spin orbit coupling (SOC) materials such as 1T${}^\prime$ phase MoTe${}_2$ is crucial for spintronics development. Here, we demonstrate wafer-scale growth of 1T${}^\prime$ MoTe${}_2$ using metal-organic chemical vapor deposition (MOCVD) with sputtered Mo and (C${}_4$H${}_9$)${}_2$Te. The synthesized films show uniform coverage across the entire sample surface. By adjusting the growth parameters, a synthesis process capable of producing 1T${}^\prime$ and 2H MoTe${}_2$ mixed phase films was achieved. Notably, the developed process is compatible with back-end-of-line (BEOL) applications. The strong spin-orbit coupling of the grown 1T${}^\prime$ MoTe${}_2$ films was demonstrated through spin torque ferromagnetic resonance (ST-FMR) measurements conducted on a 1T${}^\prime$ MoTe${}_2$/permalloy bilayer RF waveguide. These measurements revealed a significant damping-like torque in the wafer-scale 1T${}^\prime$ MoTe${}_2$ film and indicated high spin-charge conversion efficiency. The BEOL compatible process and potent spin orbit torque demonstrate promise in advanced device applications. Comment: 13 pages total, 5 figures. To be submitted |
