Science & Technology

Supplementary Figure S1 from Chao-Hung Chang et al. “Substrate properties modulate cell membrane roughness by way of actin filaments”: Images of membrane topography determined by atomic force microscopy (AFM). MEFs were seeded on the polymer coverslip-bottom μ-dishes coated with 0 or 10 μg/ml FN for 6 hours for the measurement of membrane roughness by AFM. The regions marked by the white squares in the bright-field images are displayed in the membrane topography. Scale bar, 10 μm. NANOSENSORS uniqprobe qp-SCONT AFM probes(long cantilever length 125 um, spring constant 0.01 N/m) were used.

Figure 1 from “Optical control of polarization in ferroelectric heterostructures”: Electrically induced polarization switching in the MoS2/BaTiO3/SrRuO3 junction. a, b PFM phase (a) and amplitude (b) images after application of a negative voltage pulse (−5 V, 0.5 s) to the MoS2 flake. The 12-u.c.-thick BTO film underneath the MoS2 flake is fully switched to the upward polarization, Pup. c, d PFM phase (c) and amplitude (d) images after application of several positive voltage pulses (+5 V, 0.5 s) to the MoS2 flake. BTO underneath the MoS2 flake is fully switched to downward polarization, Pdown. The polarization state of the bare BTO film (at the lower right corner) is not affected by the electrical bias. e, f The I–V characteristics of the same junction measured in the dark and during illumination. The tunneling current for the OFF state (Pup) is largely increased under illumination. Silicon AFM probes with Pt/Ir conductive coating and nominal stiffness of 3 N m−1 (PPP-EFM, NANOSENSORS) were used to perform the KPFM and PFM measurements.
