R H = -1/5 x 10 28 x 1.6 x 10-19. And off course the averaging remove the effects mentioned by Aires. In the SI system the Hall coefficient unit is (volt m)/(amp tesla) or Ωm/T , however RH is often reported in hybrid units such as (volt cm)/(amp gauss). The unit of R H is m 3 /Coulomb. You can find a good description of FET device models at the link below. MEDIUM. There are lots of measurements showing strong temperature ($T$) dependence of Hall coefficient ($R_H$) in correlated materials (eg. Any reference showing Hall coefficient and Hall angle vs temperature in a Fermi liquid metal ? Reduction dependence of R H in Pr 2 − x Ce x CuO 4 single crystals, which underwent ‘improved’ reduction as described in section 6.5.2 . Since, the resistivity at high field contain magneto-resistance contribution so do not think to consider the resitivity at any field, therefore, the longitudinal conductivity calculate by the zero field resistivity measurement and use it to evaluate the intrisic and extrinsic contributions. : the quotient of the potential difference per unit width of metal strip in the Hall effect divided by the product of the magnetic intensity and the longitudinal current density. But going from magnetic field B divided by distance d: B/d[T/m] to [G/cm]-units you have to use 1T=10000G and 1m=100cm as above. if electrical conductivity near room temperature is dominated by say thermally activated carrier hopping, then is it possible to measure Hall coefficient near room temperature ?

D. 8. b����:���sk�� �⬥�j!L�1'��� ����Ԙo�*�1 The conductivity can be considered at zero magnetic field where the AHE conductivity is the residual, or at high magnetic field where the AHE conductivity saturates. famous Quantum Hall Effect4. The importance of the Hall effect varies with the Hall coefficient, and this coefficient is determined by the fractional abundances of charged species. Definition of Hall coefficient. To represent hall coefficient in the unit cm^3/C from m^3/C, why is a factor of 10^8 multiplied to the hall coefficient in m^3/C ? ��s��6 ��c9����*a_Q=�_�UgwY�J�iu�)�BM���4�b��yKoU��O���+ �%�?�^�#�y��3XhYo�v (�#B�� � �'��?�:MS)N�5z���\��*R˨mٻ)��|�4gf\�S5rb�*_Rq�K�� @�3������H�Q�j���h(ς2�/;�>��^��4�NGx��ӿ.����K�.�����^Iu�`�/`�q�P� One tesla [T — equal to one (newton sec)/(coulomb m) ] is equivalent to ten kilogauss (kG). 4 There is also a fractional quantum Hall effect. The number of atoms per unit cell in B.C.C. They used the equation as: mobility=transconductance / Capacitance * ln2 / pi. µ p or µ n = σ n R H ———— ( 9 ) Hall mobility is defined as µ p or µ n is conductivity due to electrons and holes.
