Researchers have discovered that when certain types of semiconducting nanoplatelets - extremely thin, flat crystals - are coated with a layer of organic molecules called ligands, they curl into complex shapes, including tubes, twists and helices. This transformation is driven by the different forces the ligands apply to the top and bottom surfaces of the nanoplatelets.

Experimental Evidence for a New Type of Magnetism
Spectroscopic data suggest that thin films of a certain semiconducting material can exhibit altermagnetism, a new and fundamental form of magnetism. [...] In 2022, theorists gave a name to a new class of magnetic order: altermagnetism (see Viewpoint: Altermagnetism Then and Now). Materials that exhibit this phenomenon are predicted to have no net magnetization and an electronic band structure that is split into spin-up and spin-down bands, giving these materials properties of both antiferromagnets and ferromagnets. Despite extensive effort, strong experimental evidence for the existence of altermagnetic materials has been lacking. Such evidence has now been found by Changyoung Kim at Seoul National University in South Korea and his colleagues [1]. The researchers say that the distinctive properties of altermagnets could be useful for spin-based electronics.

Preparing for an exam! We get to take one paper full of notes. I'm happy to have reading glasses, so I can write as small as the pencil allows and cram in all the info I need and still be able to decipher it.
It's a second mid-term exam about semiconductor physics, a course I thought was obligatory but turns out it isn't. But it has some relevance to solar cells (my interest!) and it's been very chill so I don't mind taking it.
Tumblr media
Here's how it's going so far with the notes! I'm almost done with one side of the paper, just the other left to fill.

Sooo I was explaining my mother what I'm studying.
And amongst the elctronics components there are the so called "insulated gate bipolar transistors", A.K.A. "IGBT"
And she was like "isn't that the stuff about gay people?"

Up until these imperialist sanctions, China had obtained its semiconductor and other tech designs from a complex global network. Facing this U.S. blockade, the Chinese government began a robust campaign to develop its own semiconductor design capabilities. With this new Huawei success, it appears that socialist China has made a massive breakthrough.

                        SEMICONDUCTORS
        (How India is progressing in this sector)
1.What is a Semiconductor?
Semiconductors are materials which has electrical conductivity ranging between conductors and insulators. Conductors are good conductors of electricity while Insulators are bad conductors of electricity.
Tumblr media
2.Where is a semiconductor used?
Semiconductors are used in manufacture of various electronic devices like diodes, transistors and integrated circuits. The most popular use of a semiconductor is in cars. In vehicles these semiconductor chips are used to control emission systems, driver assist systems etc. Not only in electric cars these chips are also used in petrol cars.
Tumblr media
3.A Semiconductor is made up of which material?
Generally a Semiconductor chip is made up of silicon, germanium and gallium arsenide. Out of these three germanium is the oldest.
4.How will a semiconductor help?
First of all semiconductors regulate the flow of electricity and assist in making electronics function. Secondly the electrical conductivity of a semiconductor can be controlled over a wide range making them versatile for various applications. As I told you earlier that a semiconductor is not only used in electric cars but also in petrol cars, this is because semiconductors increase fuel efficiency in cars. By using semiconductors in engine control systems car manufacturers can achieve more precise control of the engine resulting in improved fuel economy and lower emissions.
So these were some common questions people ask when they hear about a semiconductor.
Now you must know that how it will help India and what steps India is taking to manufacture semiconductors in India.
At present Taiwan, USA, Japan, South Korea, China, Israel, Netherlands, UK and Germany can manufacture semiconductors. Out of these countries China and Taiwan produce a large amount of semiconductor.
More exciting thing was that USA and China were in contention with each other in this matter. During era of Donald Trump there aroused a semiconductor war between USA and China. USA wanted to disrupt China's semiconductor manufacturing and hence put a lot of sanctions on China. USA also funded Taiwan and wanted Taiwan to produce more semiconductors than China.
Tumblr media
In all this India was benefited a lot. India also wanted to develop semiconductor plants in country and facilitate ATMANIRBHAR BHARAT initiative. 
https://ism.gov.in/ this is the link of Government's India Semiconductor Mission. This mission aims at forming a semiconductor ecosystem in India.
Tumblr media
Government of India is also working on many other semiconductor initiatives like SPECS initiative. Moreover a joint venture of Vedanta electronics manufacturing giant Foxconn has finalised Dholera Special Investment Region near Ahmedabad for setting up their semiconductor display manufacturing facility.
So much progress is happening in India and surely it will facilitate India's economy and will also provide more job opportunities. India will surely emerge as a Developed nation in upcoming years and these semiconductor initiatives are like a cherry on the cake.
Watch this video for more info.
I hope you liked my article
Pls put forward your views in comment section
Till then PEACE OUT........

1. At the VLSI Symposium 2023, which will be held next month, Intel will demonstrate the PowerVia technology verification chip.
2. On May 5th, Samsung Electronics is expected to surpass its main competitor TSMC in the field of chip foundry within 5 years.
3. According to media reports, Meta recruited a team from the British artificial intelligence chip company Graphcore. The team previously worked in Oslo, Norway, and was developing AI networking technology at Graphcore until late last year.
4. On May 5, 2023, semiconductor product companies Alpha and Omega Semiconductor once fell by 11.64% in intraday trading, and once touched $20.64. The stock price hit a new low since November 18, 2020.
5. Following in the footsteps of #Samsung, SK Hynix and Micron, the US chip giant Qualcomm’s latest quarterly revenue fell -16.9% year-on-year to US$9.275 billion, and its net profit fell sharply -41.9%. The three major business segments of mobile phones, automobiles and IoT All have declined to varying degrees, and its forecast data for the third fiscal quarter is also lower than market expectations.

The new theory is based on a combination of two properties of strange metals. First, their electrons can become quantum mechanically entangled with one another, binding their fates, and they remain entangled even when distantly separated. Second, strange metals have a nonuniform, patchwork-like arrangement of atoms.
