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 ...
The market for the lesser grade is growing more quickly than for monocrystalline silicon. By 2013, polycrystalline silicon production, used mostly in solar cells, was projected to reach 200,000 metric tons per year, while monocrystalline semiconductor grade silicon was expected to remain less than 50,000 tons per year.

Not all things cost more today than in the 1970s. Here’s how inflation has affected prices, and how some goods cost older generations more.
The company exited Q2 with a net loss of $372.2 million, which is substantially higher than the prior year's $144.7 million loss. The situation is made worse by the company's Q2 negative gross ...
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 inflation.
Compared to the casting of polycrystalline ingots, the production of monocrystalline silicon is very slow and expensive. However, the demand for mono-Si continues to rise due to the superior electronic properties—the lack of grain boundaries allows better charge carrier flow and prevents electron recombination [ 5 ] —allowing improved ...
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 ...
