Good screening or bad screening......

Asked by Jianjun Mao on 2019-04-25

Dear Nick,

Hi, Nick,today I have read your talk_3(2018). In page 9:

What does a metallic electrode require:
1 Bad screening ! many extra electrode layers
2 Good screening ! few extra electrode layers

What does a semi-conducting electrode require:
1 Bad screening ! many extra electrode layers
2 Good screening ! few extra electrode layers

Does this mean we do not need a very long scattering region.....i.e. few extra electrode layers can give a good sceening....? A little confused.
