\u00a0<\/span><\/h3>\nThe research team is set to advance microchip technology by working with transition metal oxides (TMOs) instead of traditional silicon. TMOs have advantages such as high-temperature superconductivity, colossal magnetoresistance, metal-insulator transition, which promise great advances for the chip technology of the future.<\/span>\u00a0<\/span><\/p>\nSpecifically, the researchers focused on barium tin oxide (BaSnO3), a material that combines optical transparency with high electrical conductivity. For some time, scientists have been trying to elicit semiconductor-like properties from transition metals and transparent oxides like BaSnO3. This is because they offer groundbreaking advantages for optoelectronic elements compared to silicon. For example, these transparent, conductive perovskite oxides can create switching elements with directly linked electrical and optical properties. It could then be possible to produce transistors that can be switched with light.\u00a0<\/span>\u00a0<\/span><\/p>\nKnowledge of interfaces is necessary<\/span>\u00a0<\/span><\/h3>\nMicrochips are made from a combination of different substances, having physical properties that differ on the surface compared with their interior. To understand their function, therefore, scientists must have knowledge about what happens in the thin adjacent layers \u2013 the interfaces.\u00a0<\/span>\u00a0<\/span><\/p>\nUnique phases can occur at the interfaces of materials, with the team detailing many advances in the understanding of the surface-state electronic properties of BaSnO3.<\/span>\u00a0<\/span><\/p>\nThe researchers used angle-resolved photoemission spectroscopy at the beamline of the Swiss Light Source to \u201cdiscover the two-dimensional electronic state of BaSnO3, which opens up new prospects for this class of materials,\u201d stated Eduardo Guedes, co-author of the study.\u00a0<\/span>\u00a0<\/span><\/p>\nNow, the team aims to discover which other materials exhibit similar properties, to help innovate computer technology for the future, and to create potential candidates for the optical microchips of the future.<\/span>\u00a0<\/span><\/p>\nBut silicon is far from being an outdated technology, Radovic stressed. It is in fact highly developed and efficient. \u201cHowever, computer technology based on transition metal oxides is much more powerful and versatile \u2013 its time will come.\u201d<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"Researchers have used the Swiss Light Source to help reach a vital turning point in innovating computer technology.<\/p>\n","protected":false},"author":18,"featured_media":28168,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[830],"tags":[24128],"acf":[],"yoast_head":"\n
