The phrase "a larger density of" is correct and usable in written English.
It can be used when discussing the concentration or amount of something within a specific area or volume.
Example: "The study found a larger density of trees in the northern region compared to the southern region."
Alternatives: "a higher concentration of" or "an increased density of".
In this paper Ar+ ions were used to create a larger density of surface defects, which were then characterized by X-ray photoelectron spectroscopy and near-edge X-ray absorption fine structure spectroscopy.
Having a larger surface-to-volume ratio in nanostructures means a larger density of surface states.
Large value of barrier height reduces the current collection probability and, to compensate reduced current, the matrix requires a larger density of Si QDs embedded [1, 7].
Furthermore, there appears to be a peak of positive-induced absorption at 600 nm which is attributed to a larger density of the coupled states at the particular probing wavelength.
At low excitation power, the PL signal is dominated by localized exciton recombination, whose energy distribution shrinks with increasing Bi, moving from a set of quasi-discrete energy levels to a quasi-band formation with a larger density of states (see illustration in the top of Figure 4 inset), and hence resulting in an enhanced contribution to the PL spectrum.
Community structures or modules are defined when a larger density of links exists within a specific part of the network than outside it [ 9].
In the εs = 125, an increase in the transformation frequency of γ → ε leads to a large density of intersecting zones of ε-phase crystals.
The crystals were polished to a mirror finish, which results in a large density of defects at the surface and thus a high surface recombination velocity.
This is attributed to the presence of a large density of interface states.
They reveal a large density of wavy walls from which several climbing dislocations are emitted.
The alloying effect generates point impurities in the host matrix, grain refinement creates a large density of grain boundaries, while nanocomposites create a large amount of new interfaces.
