Second, the (001) surface is oxidized by the oxygen dissolved and contained in the hydrofluoric acid solution during the oxide removal process and the oxidized parts by the dissolved oxygen are to be removed by the hydrofluoric acid again. Hence the flatness of the resulting (001) surface decreases because of the surface etching with the process described above. Furthermore, in the cleaning and hydrogen termination treatment for the (001) surface by using hydrofluoric acid solution, it is unable to avoid that a surface strain is produced due to the repulsive force between the hydrogen atoms in the dihydride molecules formed on the surface or the intermolecular interaction between the precursor molecules formed on the surface during the removal process of the oxidized surface film. These strain contained inBreadcrumb

Texas HUB Program

Definition of Historically Underutilized Business (HUB)

A HUB is a business that is formed for the purpose of making a profit and that is otherwise a legally recognized business organization under the laws of Texas. A HUB must be at least 51 percent owned by one or more persons who are economically disadvantaged due to their identification as members of certain groups. The groups include Black Americans, Hispanic Americans, Asian Pacific Americans, Native Americans, Service Disabled Veterans and Women. These individuals must have a proportionate interest and demonstrate active participation in the control, operation, and management of the business' affairs. A HUB must also have its principal place of business in the State of Texas.
