Quantum Tunneling and Technology: From Flash Memory to Satellite TV and Appliances

In this video we talk about what "oh so mysterious" quantum tunneling actually is and how it is used in technologies such as flash memory and zener and tunneling diodes. For more information about flash memory and quantum tunneling specifically see this blog post: https://atomsandsporks.com/2020/04/19/quantum-tunneling-and-flash-memory/ Technical Caveat #1: As I am providing a conceputal overview I hint that in a Zener of Tunnel diode one has a sequence of three different layers (semiconductor #1 - insulatory - semiconductor #2). In reality these devices are all made with a single piece of silicon with the quantum states being different because of added impurities which are confined to only one side of the device (a so-called "doped PN junction")
