<h3><a name="evol"></a>Evolution of Resistance Concepts</h3>
|
||||
<p><b>Electrical characterization</b> of materials evolved in three levels of understanding. In the early 1800s, the resistance <i>R</i> and conductance <i>G</i> were treated as measurable physical quantities obtainable from two-terminal <i>I-V</i> measurements (i.e., current <i>I</i>, voltage <i>V</i>).
|
||||
Later, it became obvious that the resistance alone was not comprehensive
|
||||
enough since different sample shapes gave different resistance values. This
|
||||
led to the understanding (second level) that an intrinsic material property
|
||||
like resistivity (or conductivity) is required that is not influenced by
|
||||
the particular geometry of the sample. For the first time, this allowed scientists
|
||||
to quantify the current-carrying capability of the material and carry out
|
||||
meaningful comparisons between different samples.</p>
|
||||
<p>By the
|
||||
early 1900s, it was realized that resistivity was not a fundamental material
|
||||
parameter, since different materials can have the same resistivity. Also,
|
||||
a given material might exhibit different values of resistivity, depending
|
||||
upon how it was synthesized. This is especially true for semiconductors,
|
||||
where resistivity alone could not explain all observations. Theories of electrical
|
||||
conduction were constructed with varying degrees of success, but until the
|
||||
advent of quantum mechanics, no generally acceptable solution to the problem
|
||||
of electrical transport was developed. This led to the definitions of carrier
|
||||
density <i>n</i> and mobility <i>µ </i> (third level of understanding) which are capable of dealing with even the most complex electrical measurements today.<a href="http://www.eeel.nist.gov/812/fig1.htm"><img src="../images/fig1s.jpg" align="right" hspace="10" vspace="70" border="0" alt="Schematic of the Hall effect in a long, thin bar of semiconductor with four ohmic contacts. The direction of the magnetic field B is along the z-axis and the sample has a finite thickness d"></a></p>
|
||||
<h3><a name="lore"></a>The Hall Effect and the Lorentz Force</h3>
|
||||
<p>The
|
||||
basic physical principle underlying the Hall effect is the Lorentz force.
|
||||
When an electron moves along a direction perpendicular to an applied magnetic
|
||||
field, it experiences a force acting normal to both directions and moves
|
||||
in response to this force and the force effected by the internal electric
|
||||
field. For an <i>n</i>-type, bar-shaped semiconductor shown in <a href="http://www.eeel.nist.gov/812/fig1.htm">Fig.1</a>, the carriers are predominately electrons of bulk density <i>n</i>. We assume that a constant current <i>I</i>
|
||||
flows along the x-axis from left to right in the presence of a z-directed
|
||||
magnetic field. Electrons subject to the Lorentz force initially drift away
|
||||
from the current line toward the negative y-axis, resulting in an excess
|
||||
surface electrical charge on the side of the sample. This charge results
|
||||
in the Hall voltage, a potential drop across the two sides of the sample.
|
||||
(Note that the force on holes is toward the same side because of their opposite
|
||||
velocity and positive charge.) This transverse voltage is the Hall voltage
|
||||
<i>V</i><font size="2"><sub>H</sub></font> and its magnitude is equal to <i>IB/qnd</i>, where <i>I</i> is the current, <i>B</i> is the magnetic field, <i>d</i> is the sample thickness, and <i>q</i> (1.602 x 10<font size="2"><sup>-19</sup></font> C) is the elementary charge. In some cases, it is convenient to use layer or sheet density (<i>n</i><sub>s</sub> = <i>nd</i>) instead of bulk density. One then obtains the equation</p>

||||

</tbody></table>
|

</p>
|
||||
<p>Thus, by measuring the Hall voltage <i>V</i><sub>H</sub> and from the known values of <i>I</i>, <i>B</i>, and <i>q</i>, one can determine the sheet density <i>n</i><sub>s</sub>
|
||||
of charge carriers in semiconductors. If the measurement apparatus is set
|
||||
up as described later in Section III, the Hall voltage is negative for <i>n</i>-type semiconductors and positive for <i>p</i>-type semiconductors. The sheet resistance <i>R</i><font size="2"><sub>S</sub></font>
|
||||
of the semiconductor can be conveniently determined by use of the van der
|
||||
Pauw resistivity measurement technique. Since sheet resistance involves both
|
||||
sheet density and mobility, one can determine the Hall mobility from the
|
||||
equation</p>

<h3><a name="vand"></a>The van der Pauw Technique</h3>
|
||||
<p>In order to determine both the mobility <i>µ</i> and the sheet density <i>n</i><sub>s</sub>, a combination of a <a href="http://www.eeel.nist.gov/812/meas.htm#resi">resistivity measurement</a> and a <a href="http://www.eeel.nist.gov/812/meas.htm#halm">Hall measurement</a>
|
||||
is needed. We discuss here the van der Pauw technique which, due to its convenience,
|
||||
is widely used in the semiconductor industry to determine the resistivity
|
||||
of uniform samples (References 3 and 4). As originally devised by van der
|
||||
Pauw, one uses an arbitrarily shaped (but simply connected, i.e., no holes

or nonconducting islands or inclusions), thin-plate sample containing four

very small ohmic contacts placed on the periphery (preferably in the corners)

of the plate. A schematic of a rectangular van der Pauw configuration is

<p>To obtain the two characteristic resistances, one applies a dc current <i>I</i> into contact 1 and out of contact 2 and measures the voltage <i>V</i><font size="2"><sub>43</sub></font> from contact 4 to contact 3 as shown in <a href="http://www.eeel.nist.gov/812/fig2.htm">Fig. 2</a>.

The Hall voltage measurement consists of a series of voltage measurements with a constant current <i>I</i> and a constant magnetic field <i>B</i> applied perpendicular to the plane of the sample. Conveniently, the same sample, shown again in <a href="http://www.eeel.nist.gov/812/fig3.htm">Fig. 3</a>, can also be used for the Hall measurement. To measure the Hall voltage <i>V</i><font size="2"><sub>H</sub></font>, a current <i>I</i> is forced through the opposing pair of contacts 1 and 3 and the Hall voltage <i>V</i><font size="2"><sub>H</sub></font> (= <i>V</i><font size="2"><sub>24</sub></font>) is measured across the remaining pair of contacts 2 and 4. Once the Hall voltage <i>V</i><font size="2"><sub>H</sub></font> is acquired, the sheet carrier density <i>n</i><sub>s</sub> can be calculated via <i>n</i><sub>s</sub> = <i>IB</i>/<i>q</i>|<i>V</i><font size="2"><sub>H</sub></font>| from the known values of <i>I</i>, <i>B</i>, and <i>q</i>.</p>
|
||||
<p>There
|
||||
are practical aspects which must be considered when carrying out Hall and
|
||||
resistivity measurements. Primary concerns are (1) ohmic contact quality
|
||||
and size, (2) sample uniformity and accurate thickness determination, (3)
|
||||
thermomagnetic effects due to nonuniform temperature, and (4) photoconductive
|
||||
and photovoltaic effects which can be minimized by measuring in a dark environment.
|
||||
Also, the sample lateral dimensions must be large compared to the size of
|
||||
the contacts and the sample thickness. Finally, one must accurately measure
|
||||
sample temperature, magnetic field intensity, electrical current, and voltage.</p>
