4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer
materials
One of the defining characteristics of living organisms is their inherent ability to repair physical damage. A growing trend in biomimicry is the creation of non-living structural materials that also have the capacity to heal themselves when cut, torn or cracked. Self-healing materials which can repair damage without external human intervention could give manufactured goods longer li
2. Important Characteristics of TiO2
(1) Photocatalystic Character
- If the light energy is irrigated at TiO2, the catalyst which absorbed the light energy will activate so it oxidize and restore aspirates.
(2) Characteristic of Ultra-hydrophile
- Ultra-hydrophile is the status that befit with the surface of the material such as glass.
For many of Materials, if we drop water, it ma
material income to Korean market, we support that the influence of Chinese raw material to Korean market will be severe in the future. And the request deflection is also serious different form the season of resource and the region of the resource if we look at the characteristics of construction industry. And compare with the other industries, because the difficulty of industry’s automation and
curve shift toward applied voltage because the movement of charges is determined by applied voltage(-,+). It is known that mobile charges are generated when dielectric material has the impurities such as Na ion.
The term fast interface state refers to the fact that these defects can change their charge state relatively fast in response to changes of the gate bias. As the surface potential in a
