A first-principles calculation at the atomic level indicated that Mo facilitated hydration, whereas Sc doping facilitated the formation of oxygen vacancies.

The heat capacity C(T) of GeNTs shows a more pronounced increase with the application of external fields, especially electric field and exceeds that of CNTs. GeNTs also exhibit a lower threshold temperature for non-zero electrical conductivity attributed to their smaller energy gap, which results from easier thermal excitation of charge carriers. This property becomes more pronounced as the electrical conductivity of GeNTs increases more rapidly with temperature than that of CNTs, particularly under stronger external fields. Additionally, the thermoelectric properties of GeNTs can be further enhanced under external fields. While CNTs possess higher Seebeck coefficients and Lorenz numbers, GeNTs demonstrate distinct advantages in tunable heat capacity and conductivity, making them promising candidates for efficient thermoelectric and nanoelectronic devices.
