abstract = {Recently, new quantum effects have been studied in thin
nanograting layers. Nanograting on the surface imposes
additional boundary conditions on the electron wave function
and reduces the density of states (DOS). When the
nanograting dimensions are close to the de Broglie
wavelength, the DOS reduction is considerable and leads to
changes in the layer properties. DOS calculations are
challenging to perform and are related to the quantum
billiard problem. Performing such calculations requires
finding the solutions for the time-independent Schrödinger
equation with Dirichlet boundary conditions. Here, we use a
numerical method, namely the Method of Auxiliary Sources,
which offers significant computational cost reduction
relative to other numerical methods. We found the first five
eigenfunctions for the nanograting layer and compared them
with the corresponding eigenfunctions for a plain layer by
calculating the correlation coefficients. Furthermore, the
numerical data were used to analyze the DOS reduction. The
nanograting is shown to reduce the probability of occupation
of a particular quantum state, reducing the integrated DOS
by as much as 4.1-fold. This reduction in the DOS leads to
considerable changes in the electronic properties.},
