Can we change the threshold voltage by controlling the gate oxide thickness in a p-mos?

    \$\begingroup\$ Consult your textbook about the MOS structure and MOS transistors and look what defines the Threshold voltage. \$\endgroup\$ – Bimpelrekkie Oct 23 '16 at 19:22

Yes.

See for example

https://en.wikipedia.org/wiki/Threshold_voltage#Dependence_on_oxide_thickness

or any textbook about MOS design.
