Chemical Structure from Scientific Research

Schematic representation of a double-gated CrPS 4 bilayer transistor of the type used in this work (see Methods for fabrication details). The zoom-in panel shows a side view of the CrPS 4 crystal structure (the red, blue, yellow and orange balls represent top-layer Cr, bottom-layer Cr, P and S atoms, respectively). The double-gated geometry enables independent control of the electron density ( n e ) and displacement field ( D / ε 0 = ( D T + D B )/2 ε 0 ; D T ( D B ) is the displacement field generated by the top (bottom) gate).
