can semiconductors more conductive than metals
No. semiconductors cannot be more conductive then metals.
Which of the following represent correct order of conductivity in solids ?
(a) Kmetals >> Kinsulators < Ksemiconductors
(b) Kmetals << Kinsulators < Ksemiconductors
(c) Kmetals.,Ksemiconductors > Kinsulators=zero
(d) Kmetals < Ksemiconductors > Kinsulators≠zero
Conductivity can't be increased for semiconductors
