Apr 5, 2024, 8:15 PM

Answer the research question, how do temperature and voltage affect the conductivity of a semiconductor material?

The analysis of how temperature and voltage affect the conductivity of a semiconductor material was conducted using data visualized in two plots:
  1. Conductivity vs. Temperature: This plot shows the relationship between temperature (°C) and conductivity (S/m). The trend indicates how conductivity changes with temperature.
  2. Conductivity vs. Voltage: This plot illustrates the relationship between voltage (V) and conductivity (S/m). It highlights how conductivity varies with changes in voltage.
These plots provide insights into the behavior of semiconductor materials under different temperature and voltage conditions, contributing to understanding their electrical properties.

Test the null hypothesis which state that There is no significant relationship between temperature, voltage, and the conductivity of a semiconductor material.

The null hypothesis, which stated that there is no significant relationship between temperature, voltage, and the conductivity of a semiconductor material, was tested using ANOVA (Analysis of Variance). The results are as follows:
  • F-statistic: 102.6475
  • P-value: 0.0000
Given the P-value is less than 0.05, we reject the null hypothesis. This indicates there is a significant relationship between temperature, voltage, and conductivity in the semiconductor material.

Continue the analysis

To further analyze the relationship between temperature, voltage, and conductivity of a semiconductor material, we could consider the following steps:
  1. Correlation Analysis: Determine the correlation coefficients between each pair of variables (temperature vs. conductivity, voltage vs. conductivity) to quantify their linear relationships.
  2. Regression Analysis: Perform regression analyses to model the relationship between conductivity and each of the other variables separately. This can help in understanding how changes in temperature or voltage predict changes in conductivity.
  3. Multivariate Analysis: Explore models that include both temperature and voltage as predictors of conductivity. This can provide insights into how these variables interact to influence conductivity.
These analyses can provide deeper insights into the dynamics of semiconductor material conductivity under different conditions.

Visualize this for me

The analysis continued with a visualization of the correlation between temperature, voltage, and conductivity of a semiconductor material. A heatmap of the correlation matrix was created, providing a visual representation of the relationships between these variables. This visualization helps in understanding the linear relationships and the strength of association between each pair of variables, offering insights into how temperature and voltage individually correlate with conductivity.
