Coating of gold on silicon-
In one of the journals, the scientists of S&T have talked about an option to develop thin golden layers on a crystal silicon wafer. They have to take out the golden foil to apply them just as a kind of substrates. Other available electronic stuffs may be developed on them. The new discovery of researchers may bring about some transformation in the field of wearable items. Moreover, it also proves an improvement of similar electronics on the coming days.
One of the leading scientists, Jay Switzer has said that a significant amount of study has been conducted in the domain of wearable technologies with the use of polymer-based substrates. Some substrates also comprise crystals. They are placed into semiconductor in order to bring the flexibility. However, there may be a loss of order, maintained by silicon. As there is more than one crystal, they may have grain limits, which restrict the functioning of some electronic systems.
If we consider a semiconductor, there are holes and electrons, opposite to each other. They may also blend the stated boundaries in order to produce heat. Most of the electronic appliances are manufactured with silicon as this is more affordable item. In addition to it, the performance of this substance is also good. There is a perfect alignment of all atoms. However, while only one crystal is present, the level of flexibility is not much high.
What positive features gold mar bring to a foil-
The scientists have, at first, started their work with one silicon crystal, and after that, they have considered golden foils. As gold is present in the foil, both flexibility and durability are high. The system may be twisted almost four thousand times. But, the level of resistance cannot get altered.
Some challenges have been faced by the researchers at the time of unpeeling the thin foil layer. The bolding between silicon and gold is very strong. To get rid of the problem, photo electrochemical process is used for silicon oxidization. In this oxidization, light allows semiconductor for promoting the reaction. Several golden foils may be designed with single silicon.
The overall research is really a pleasure to the scientists, who wanted to get an affordable way for creating distinct crystals. Many people, who like to deal with such materials, may have some interest in this matter. Moreover, it also gives important data to those, who desire working on these crystals. The team of researchers, who are involved in this issue, includes expert in the field of chemistry and engineering. And with the efforts of all these professionals, the research has been successful.
