Probing the electric double layer (EDL)
formation for synapsin
1 condensates. (a) A scheme of the layered structure involving hexagonal
boron nitride (hBN) as an atomically thin dielectric separator between
synapsin 1 condensates and their mirror charges in graphene. Red arrows
indicate the electric fields introduced by the synapsin condensates
(top, hBN region) and by the gate electrode (bottom, gate dielectric
SiO2). (b) Measurements of the change in the electron concentration
as a function of time Δe–(t), with varying hBN layer thickness between 3
and 40 nm, as indicated on the right side of the graph. (c) Double
logarithmic plot of the saturation Δe–(t) values as the function of d. Solid line represent 1/d fit (d, dielectric thickness).
