The phrase "a very small thickness of" is correct and usable in written English.
It can be used when describing the minimal measurement or extent of a material or layer.
Example: "The artist applied a very small thickness of paint to achieve a delicate texture on the canvas."
Alternatives: "a thin layer of" or "a minimal thickness of".
"We demonstrate that [the nanoantenna array can] increase significantly the overall spectral efficiency of solar cells with a very small thickness". they say.
Figure 1b shows that the graphene sheets are highly transparent with folding at the edges, suggesting a very small thickness.
Very small thickness of the microchip is in particular helpful to acquire the better images of biomolecules near the bottom wall in the prism-type TIRFM using an upright microscope.
However, since the individual "horns" are very small (thickness of 2 nm and the length about 10 nm), they are too fragile to host larger polymer beads.
Secondly and more importantly, the temperature varies sharply from the top to the bottom surface over the very small thickness of the Greenland island compared to its length.
Due to the presence of big three-dimensional micro-crystallites of Thy on glass, the broad band at 250 to 600 cm−1 which is associated with the molecular vibrations in the substrate is absent in Figure 3b, while in the case of Thy on the graphene-on-silica substrate (Figure 3a), the band at 250 to 600 cm−1 is available due to the very small thickness of flakes of Thy.
Such findings have explained the very small thickness of the stratum corneum after 30 tape-strips observed on optical microscopy images).
Due to very small thickness of the muscularis mucosa and the similarity between the muscularis mucosa and submucosa optical properties, the muscularis mucosa will be included in the submucosa layer in our model.
The points in Fig. 5c all lie on a line of very small thickness, illustrating that the system is deterministic and neither artifacts nor noise is responsible for the observed irregularity in the interspike interval pattern.
The noisy baseline and rather broad FePt peaks are probably due to the very small thickness (7 nm) of the FePt film.
