11. However, the vacuum electrostatic potential is not flat due to a difference in work function . 12. A few weeks after launch, an optimized GPU miner for CryptoNight proof-of-work function was developed. 13. The most common believed scenario is that the Work Function Algorithm is " k "-competitive. 14. The electron affinity of a surface is closely related to, but distinct from, its work function . 15. This is what couples do they go to each other's boring work functions . '" 16. Using such instrument, one can acquire elemental images with chemical state sensibility or work function maps. 17. Hexaborides show low work function , around 2.5 eV . They are also somewhat resistant to cathode poisoning. 18. To emit thermionically at zero degrees Celsius, a material needs a work function of around 0.3 electronvolts. 19. This occurs because the thermal energy given to the carrier overcomes the work function of the material. 20. Just like the work function , the Volta potential depends sensitively on surface state, contamination, and so on.
