  "summary": "Researchers have developed a new method to directly observe the electrical potential distribution in working graphene devices, using X-ray Photoelectron Spectroscopy (XPS). By examining the electrical landscape, they identified regions with steep electric fields and flatter regions with weaker fields, determining how oxide coatings modify this landscape. The study found that metal oxide layers flatten the electrical landscape through a process called p-type charge-transfer doping, reducing local electric fields by more than 50%. This breakthrough allows for improved device design, particularly for spintronic devices and neuromorphic computing hardware, which are highly sensitive to local electric fields. The findings were published in Rep. Prog. Phys. 89 060502.",
