Thin film underlayer effects on mass resolving power in laser-assisted atom probe tomography
The effects of varying Co thickness on the mass resolving power for Cu in a multilayer stack are characterized by laser-assisted atom probe. As the Co layer thickness increased, Cu exhibited poorer mass resolving power. By reducing the pulse repetition rate from 250kHz to 10kHz, the mass resolving p...

description | The effects of varying Co thickness on the mass resolving power for Cu in a multilayer stack are characterized by laser-assisted atom probe. As the Co layer thickness increased, Cu exhibited poorer mass resolving power. By reducing the pulse repetition rate from 250kHz to 10kHz, the mass resolving power improved to match that of Cu with no Co underlayer. These results support that thermal mechanisms for field evaporation dominate in this Co–Cu multilayer, which is a common architecture in giant magneto-resistance thin film devices.
•Multilayer thin film stacks of different thermal conductivity materials were studied.•Increasing thickness of the insulating layer decreased mass resolving power.•Lowering the laser pulse rate increased the mass resolving power.•Demonstrates the ability to study stacks of different conductivity materials. |
