By carrying out Monte Carlo simulations, we study step bunching induced by flow in solution during dissolving. For simplicity, we assume that steps are straight and express an array of steps as dots on one-dimensional vicinal face. We consider a two square lattice to represent the diffusion field in a solution. The diffusion of atoms in a solution is expressed as the hopping of atoms on lattice sites. During dissolving, the step bunching occurs in the case of step-up flow. In an early stage, the width of the fluctuation of step distance, w, increases with time as t α . The exponent α is equal to 1/2 in the initial stage. Then, α decreases and is approximately given by 1/4. In a late stage, the width w is saturated. The saturated value of w increases with the strength of flow.

The solubility curve of Lithium Formate Monohydrate (LFM) crystal was measured using laser schlieren technique in 300-320K. According to the effects of temperature to solubility, solution heat of LFM crystal was calculated. Differential scanning calorimetry (DSC) analysis of LFM was performed in the temperature range of 300-500K. Endothermic peaks of the DSC curve of LFM crystal were assigned, and fusion heat and hydration activation energy of LFM were calculated.

We study step bunching on a vicinal face in solution growth. Assuming that steps are straight, we consider a two-dimensional diffusion filed to represent a solution and a onedimensional vicinal face. The steps are expressed as dots in the vicinal face. Taking account of a flow in a solution, we numerically solve the diffusion equation and the Navier-Stokes equation in the solution, and determine step velocities. If a flow in a solution is absent or is in the step-up direction, a vicinal face is stable. When the flow is in the step-down direction, the vicinal face is unstable and step bunching occurs. In the initial stage, small bunches are formed. Then, owing to the coalescence of small bunches, large bunches are formed.
