A 1.4 nm silicon cube holds approximately 137 atoms and 1,918 electrons. This scale is relevant as Samsung targets 1.4 nm mass production by 2027, with Intel also advancing. Visualizing such minute transistors requires specialized electron microscopes, not optical ones. The author expresses strong skepticism, deeming this “science-fiction” technology unbelievable due to the few electrons involved and questioning its practical existence, akin to dismissing Mars travel as mere fantasy.Here’s how we can estimate it:So, in a 1.4 nm cube of silicon, there would be approximately 137 atoms.Why would you want to know that? Because Samsung has said it would bring its 1.4
