(PAS), which is capable of extremely high detection sensitivities with a compact and relatively low-cost absorption detection module.2This technique is also based on an optical absorption process but differs from laser-absorption spectroscopy in the physical phenomenon used for the detection of the ...
Our simple decoupling method has captured the main operation principle of the device. However, some detailed questions still remain for discussion. For example, the heated chromium pad can generate a temperature gradient in graphene from Cr side to Au side, which contributes to a response that is...
