Electrical Transport of Nb‐Doped MoS2 Homojunction P–N Diode: Investigating NDR and Avalanche Effect
Small, Volume 22, Issue 9, 12 February 2026.Niobium (Nb)‐doped molybdenum disulfide (MoS2) p‐type–n‐type (p–n) homojunction diodes are engineered using thickness‐controlled homo‐interfaces. Current–voltage (I–V) characteristics reveal gate‐tunable rectification, wavelength‐dependent photoresponse, and low‐bias switching.
