A novel fabrication of microelectronic nose based on ZnO nanowires and ZnO surface modifications including ZnO-ZnAl2O4 core-shell nanowires and ZnO-Zn2TiO4 core-shell nanowires gas-sensing elements operated at room temperature is reported. By combining vapor-phase transport processes and atomic laye...
