What are the Key Parameters Affecting Coulomb Blockade?
Several parameters influence the occurrence and characteristics of coulomb blockade in nanodevices:
1. Capacitance: Smaller capacitance increases the charging energy, making coulomb blockade more pronounced. 2. Temperature: Lower temperatures reduce thermal energy, making it easier to observe coulomb blockade. 3. Source-Drain Voltage: The voltage difference between the source and drain terminals can affect the onset of the blockade. 4. Tunnel Resistance: Higher resistance can enhance the blockade effect by limiting electron flow.
