Scientists make thin films with disruptive electronic properties, Scientists have made barium zirconium sulfide (BaZrS3) thin films and confirmed that these materials have interesting electronic and optical properties, as predicted by theorists.
Foil combines very strong light absorption with good payload transportation and is therefore ideal for applications such as photovoltaics and LEDs.
For example, experimental results show that BaZrS3 films are far more efficient at converting sunlight to electricity than conventional silicon-based materials of the same thickness.
For decades, there were only a few semiconductor materials they used, the dominant material being silicon, the researchers said. Our thin films open new directions for semiconductor research. The opportunity to discover the potential for a whole new class of material.
BaZrS3 belongs to the category of ingredients known as chalcogenide perovskites. This is a non-toxic compound that is common on earth. In recent years, theorists have calculated that various chalcogenide perovskites must have useful electronic and optical properties, and this prediction has aroused the interest and imagination of researchers such as Zen.
BaZrS3 is not entirely new material. Zeng looked at the complex history and found information from the 1950s.
One researcher says that it has existed for more than half a century. Under a previous study, a company in Niagara Falls produced it in powder form. I think people don’t pay attention to.
For applications such as photovoltaic and LED, thin and non-dust film is required. Therefore, this is the Zeng team that tried to make it.
The researchers produced their BaZrS3 film with a laser to heat and vaporize barium zirconium oxide. Steam is stored on the surface of sapphire to form a film and then converted to the final material by a chemical reaction called sulfurization.
Now that we have the BaZrS3 thin film, we can examine its basic properties and find out how it can be used in solar cells, LEDs, optical sensors and other applications, researchers said.
