Nanofrictional behavior of amorphous, polycrystalline and textured Y-Cr-O films

Influence of plasma kinetic energy during the pulsed laser deposition of borophene films on silicon (100)

“…The probe had a diamond-like carbon coating [Budgetsensors Multi75DLC, with free resonance frequency of ∼75 kHz and hardness >20 GPa], obtaining AFM topographic surface images and friction force vs. load (nN) curves; the procedure for the nanofriction test was reported in ref. 36 and 37 .…”

Deconvolution analysis of B 1s orbitals showed similar borophene spectra (at 189.4 eV) intensities for the B01 and B02 samples, and the B03 sample showed a slight decrease [see Fig.…”

A comprehensive review on the ferroelectric orthochromates: Synthesis, property, and application

“…Different friction coefficients of ferroelectric YCrO 3 samples, poly-crystalline, textured, and non-ferroelectric Y-Cr-O films were investigated [125]. The analyses showed that the ferroelectric YCrO 3 thin film on Pt(150 nm)/TiO 2 (30 nm)/SiO 2 /Si(100) substrate was poly-crystalline and had a lower friction coefficient than that on SrTiO 3 (110) substrate which was highly textured.…”

As a candidate for ferroelectric memories, poly-crystalline YCrO 3 films have more advantages due to the lower friction coefficient [125].…”

“…A hysteresis of polarization-electric (P-E) loop of the polarization curve presents at 300, 325, and 350 K [72]. Previous studies of YCrO 3 compound focused mainly on polycrystals [74,98,[100][101][102][103][104][105][106][107][108], nanocrystals [109][110][111][112][113][114][115], and thin films [72,83,86,[116][117][118][119][120][121][122][123][124][125][126][127][128][129]. The lack of high-quality and large-scale single-crystalline samples has been a long-standing issue for realizing potential applications to some extent and studying their intrinsic physical properties [130][131][132][133][134][135][136][137].…”
