Single-electron devices can be built using a metal nanoparticle as an island between two electrodes: one electron at a time is passing the nanoparticle "island" between the electrodes = the island behaves as a Coulomb blockage. When a Pb nanoparticle is used in a device, each Coulomb staircase step is measured to be 0.52 eV (the radius of Pb particle is 4.2 nm).a) Calculate what is the maximum temperature (in K) where the Coulomb blockage phenomenon can be observed for a such a Pb nanoparticle single-electron device (hint: thermal energy kBT)?b) What is the maximum temperature where the Coulomb blockage phenomenon can be observed for a bulk Pb electrode with 1.0 cm2 surface area (capacitance of bulk lead is 16.1 μF/cm2)?

Answer from: Quest

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.

Answer from: Quest

Electron equations of the given changes are as follow,a) cu → cu⁺² + 2e⁻b) mg⁺² + 2 e⁻ → mgc) cl⁻ → cl + 1e⁻d) s + 2 e⁻ → s²⁻e) o²⁻ → o + 2 e⁻f) p + 3 e⁻ → p³⁻g) fe²⁺ → fe³⁺ + 1 e⁻h) s²⁻ → s⁴⁺ + 6 e⁻

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
