these electronic components now only a handful of nanometres in size. (There are around 12 billion transistors in the postage-stamp sized central chip of modern smartphones.)  \nHowever, in even smaller devices, the channel that the electrons flow through has to be very close to the interface between the semiconductor and the metallic gate used to turn the transistor on and off. Unavoidable surface oxidation and other surface contaminants cause unwanted scattering of electrons flowing through the channel, and also lead to instabilities and noise that are particularly problematic for quantum devices.  \n“In the new work we create transistors in which an ultra-thin metal gate is grown as part of the semiconductor crystal, preventing problems associated with oxidation of the semiconductor surface,”says lead author Yonatan Ashlea Alava.  \n“We have demonstrated that this new design dramatically reduces unwanted effects from surface imperfections, and show that nanoscale quantum point contacts exhibit significantly lower noise than devices fabricated using conventional approaches,” says Yonatan, who is a FLEET PhD student.  \n“This new all single-crystal design will be ideal for making ultra-small electronic devices, quantum dots, and for qubit applications,” comments group leader Prof Alex Hamilton at UNSW.  \nTHE CHALLENGE: ELECTRON SCATTERING LIMITS HIGH-FREQUENCY COMPONENTS  \nSemiconductor devices are a staple of modern-day electronics. Field-effect transistors (FETs) are oneof the building blocks of consumer electronics, computers and telecommunication devices.  \n[https://www.miragenews.com/homegrown-semiconductors-for-faster-smaller-616733/ 2/8](https://www.miragenews.com/homegrown-semiconductors-for-faster-smaller-616733/ 2/8)  \n10/5/21, 10:16 PM Homegrown semi","cbCaihY8bKgh6pkR","https://ap.wps.com/l/cbCaihY8bKgh6pkR","pdf",567525,8,"English","# Homegrown semiconductors for faster, smaller electronics\n## Growing components to reduce oxidation scattering\n## Smaller devices, noisier operation\n## Electron scattering limits high-frequency components","[{\"question\":\"What problem does the UNSW approach aim to solve in smaller semiconductor devices?\",\"answer\":\"It targets unwanted scattering and noise caused by semiconductor surface oxidation and contaminants that become increasingly problematic in ultrasmall devices.\"},{\"question\":\"How does the new transistor design reduce surface-related imperfections?\",\"answer\":\"It grows an ultra-thin metal gate as part of the semiconductor crystal, preventing issues associated with oxidation of the semiconductor surface and lowering noise compared with conventional fabrication.\"},{\"question\":\"Why are these improved components valuable for high-frequency and quantum applications?\",\"answer\":\"Higher electron mobility supports better high-frequency performance, while reduced noise makes the resulting nanoscale quantum point contacts suitable for quantum dots and qubit applications.\"}]","Homegrown semiconductors for faster, smaller electronics - research highlights | PDF",1789150466]
