WebJun 18, 2024 · Yes, the standard reduction potential does depend on temperature. The definition of the standard reduction potential is stated in Ref.1 as: ... the Nernst equation will only be valid if I use the same T (Temperature) value at which my E∘ (used in that specific Nernst eq) is defined? i.e. The Temperature parameter of a Nernst equation is a ... WebJun 30, 2024 · The absolute value of the Nernst limit increases with the increase of temperature, the coupling factor γ does not change, so the sensitivity value of the device increases. Although the carrier mobility decreases as the temperature increases, as shown in Figure 7 , the result is the change of threshold voltage rather than the sensitivity [ 20 ]. floristics wildberg
