Key Points

This work examines the electronic properties of ultranarrow germanene nanoribbons (GeNRs) in relation to metal contact characteristics.
Performed calculations to compare the work function of GeNRs with pristine Ag(111).
Analyzed interfacial charge modulation and electronic states in the GeNR/Ag(111) system.
GeNRs exhibit a moderately higher work function compared to pristine Ag(111).
The GeNR/Ag(111) system provides an atomically defined platform for studying charge modulation and resonant tunneling.
Mechanical properties of GeNRs were assessed in relation to substrate stabilization.

Implication

Calculations reveal interfacial charge modulation in Germanene Nanoribbons on Ag(111), suggesting engineering applications.
