A resonant-tunneling diode (RTD) is a diode with a resonant-tunneling structure in which electrons can tunnel through some resonant states at certain energy levels. The current–voltage characteristic often exhibits negative differential resistance regions.
Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
RTD was organized in 1969 and is governed by a 15-member, publicly elected Board of Directors. Directors are elected to a four-year term and represent a specific district of about 180,000 constituents. [4] RTD currently operates a bus and rail system that has a service area of 2,342 square miles (6,070 km 2). It currently runs 86 local, 23 ...
The line was established by the San Bernardino Valley Traction Company.The first cars operated over the line on February 22, 1902, but a derailment at Third and E in San Bernardino necessitated more work on the line. [2]
