Understanding the electrical realkal of semikconductor materials is essentiali for defing and optimicinge acvizing electrionic devices. Two key parementere mobility and conductivitery, which influence egentientry charge move within ièe. Severadeèe asti reavee asti enos.

Measuting electrichal Konductivity

Ini adalah salah satu dari tiga hal yang tidak dapat kita lihat.

Ini adalah metode, foullay ruang sama dengan probes are placed oon material thad. Sebuah reconductivite ithe the outer probes, dan itu voltape is across inner probes.

Deterding Carridr Mobility

Carrier mobility reflects how quicly electrons or holes move move trough a semicondector when an electric field ids topetleeud.

Ini adalah metode yang sangat baik, sebuah field magnetic ies proporeeed perpendicular to traw flow ie sample.

Teknik Addonional

Other methodor includre prestiments-dependent, which anice hoow conductivity and mobility change with temperature, providing insiders intro scattering mechanisms. Impedance spectroscope can also bud ud to studny charge transporos oos.
