As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
Conversely, silicon is robust, cheap, and easy to process, whereas GaAs is brittle and expensive, and insulation layers cannot be created by just growing an oxide layer; GaAs is therefore used only where silicon is not sufficient. [2] By alloying multiple compounds, some semiconductor materials are tunable, e.g., in band gap or lattice constant ...
These include hydrogenated amorphous silicon and upgraded metallurgical-grade silicon (UMG-Si) used in the production of low-cost, large-area electronics in applications such as liquid crystal displays and of large-area, low-cost, thin-film solar cells. Such semiconductor grades of silicon are either slightly less pure or polycrystalline rather ...

It’s not surprising to find a few cars on this list of the world’s most expensive things. In 2018, a 1962 red Ferrari GTO sold to an anonymous buyer at Sotheby’s auction in Monterey for $48. ...
The price represents a 48% premium to the undisturbed market value as of April 22, 2022, in cash and stock transaction, valuing Silicon Motion at $3.8 billion. Silicon Motion makes NAND flash ...
Monocrystalline silicon, often referred to as single-crystal silicon or simply mono-Si, is a critical material widely used in modern electronics and photovoltaics. As the foundation for silicon-based discrete components and integrated circuits , it plays a vital role in virtually all modern electronic equipment, from computers to smartphones.
With the current inflation rate, things that cost a dollar 50 years ago would approximate cost $7.03 today. Not everything was cheaper in 1972, but most things were even when adjusted for ...
