Created the smallest transistor

01.11.2016

Physicists from the University of Berkeley in the US have created the world's first transistor with a gate of about one nanometer. This is an order of magnitude less than the smallest transistors in use today. An article by scientists was published in the journal Science, the university website briefly talks about the development.

The materials for the transistor were molybdenum sulfide and carbon nanotubes, it was this combination that made it possible to radically reduce the size of the gate - it is this element of the device that controls its conductivity. The design involves three layers: a silicon substrate, zirconium dioxide plates with a carbon nanotube passing through them, and a thin film of molybdenum disulfide.

Due to the higher resistance of molybdenum disulfide than silicon, the gate of even a single carbon nanotube creates a strong electric field to prevent electrons from "jumping" from one end of the transistor to the other using quantum tunneling.

"We have created the smallest transistors to date. The nanometer gate device proves that the right choice of materials allows further reduction in the size of electronics," said research team member Ali Javey.

It is impossible to use such transistors for electronics right now, since there is no technology for printing them and embedding them in chips, but this is a task for the future.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Container for carrying computers 05.11.2002

For especially restless computer geeks, the American company "CaseAce Products" produces a whole series of bags, suitcases and bags that allow you to carry even large desktop computers.

If your monitor is flat, on liquid crystals, there are no problems at all: on one shoulder you hang a bag with a monitor lined with foam, on the other - a kind of harness in which the system unit is placed, tied with a belt, and in the side mesh pocket - a keyboard, mouse and all required cables.

If you have an old-fashioned monitor, on a cathode ray tube, you will have to take in hand a knot in which a bulky monitor is held by straps.
