Experiment: Hall-effekt i halvledare (230 V, 50/60 Hz), grundläggande utrustning – 8000728

Objective: Investigating electrical conduction mechanisms in doped germanium with the Hall effect The Hall effect occurs in electrically conductive materials located in a magnetic field B. The Hall voltage’s sign changes depending on whether the same current I is borne by positive or negative charge carriers. Its value depends on the charge carrier density. The […]

Experiment: Elektrisk ledning i halvledare (230 V, 50/60 Hz), Komplement – 8000726

Objective: Determine band separation in germanium Semiconductors only exhibit measurable electrical conductivity at high temperatures. The reason for this dependence on temperature is the band structure of the electron energy levels, which comprise a conduction band, a valence band and an intermediate zone, which in pure, undoped semiconductor materials cannot be occupied by electrons at […]

Experiment: Fotokonduktivitet (230 V, 50/60 Hz) – 8000776

Objective: Record the characteristic curve for a photoresistor Photoconductivity utilises absorption of light by means of the inherent photoelectric effect in a semiconductor to create electron-hole pairs. One specific semiconductor mix which exhibits the photoelectric effect particularly strongly is cadmium sulphide. This material is used in the construction of photoresistors. In this experiment, a CdS […]
