Which outcome increases when electrons encounter narrower potential barriers?

💡 Explanation

Tunneling probability increases as barrier width decreases because wave functions decay less within a narrower barrier, therefore electrons more readily penetrate; rather than reflection increasing from refraction effects which require interfaces.
