Guide layout creating apparatus, guide layout creating method and recording medium
In one embodiment, a guide layout creating apparatus includes a selection module that selects a first point as a point on which a guide to array a plurality of particles in a first array is arranged. The apparatus further includes a calculation module that calculates first free energy when the plurality of particles are arrayed in the first array by the guide arranged on the first point, and second free energy when the plurality of particles are arrayed in a second array by the guide arranged on the first point, a type of the second array being different from a type of the first array. The apparatus further includes a determination module that determines whether the first point is employed as the point on which the guide is arranged on the basis of the first free energy and the second free energy.
1. A guide layout creating apparatus comprising:
a selection module that selects a first point as a point on which a guide to array a plurality of particles in a first array is arranged;
a calculation module that calculates first free energy when the plurality of particles are arrayed in the first array by the guide arranged on the first point, and second free energy when the plurality of particles are arrayed in a second array by the guide arranged on the first point, a type of the second array being different from a type of the first array; and
a determination module that determines whether the first point is employed as the point on which the guide is arranged on the basis of the first free energy and the second free energy.
2. The apparatus of claim 1 , wherein the determination module determines to employ the first point as the point on which the guide is arranged on a condition that the first free energy is lower than the second free energy.
3. The apparatus of claim 1 , wherein patterns of the first and second arrays are hexagonal close-packed patterns.
4. The apparatus of claim 1 , wherein the guide is a chemical guide or a physical guide.
5. The apparatus of claim 1 , wherein
the selection module selects a second point as a point on which the guide is arranged;
the calculation module calculates third free energy when the plurality of particles are arrayed in the first array by the guide arranged on the second point, and fourth free energy when the plurality of particles are arrayed in the second array by the guide arranged on the second point; and
the determination module determines to employ the first point as the point on which the guide is arranged when a first difference obtained by subtracting the first free energy from the second free energy is larger than a second difference obtained by subtracting the third free energy from the fourth free energy.
6. The apparatus of claim 1 , wherein the selection module automatically selects the first point at random.
7. The apparatus of claim 1 , wherein the selection module selects a first region as a repetition unit of arrangement of the guide, and selects the first point in the first region.
8. The apparatus of claim 1 , wherein
the calculation module calculates fifth free energy when the plurality of particles are arrayed in a third array in rotary symmetry to the first array by the guide arranged on the first point; and
the determination module determines whether or not the first point is employed as the point on which the guide is arranged on the basis of the first free energy and the fifth free energy.
9. The apparatus of claim 8 , wherein the determination module determines to employ the first point as the point on which the guide is arranged on a condition that the first free energy is lower than the fifth free energy.
