Kupferdünnfilm auf Saphirsubstrat für Graphenwachstum

High quality large-area single crystal copper substrate is an effective method for preparing high-quality large-area single crystal graphene. There are several main methods for preparing single crystal copper: 1) Commercial single crystal copper is mostly produced by using the high-temperature hot casting mode continuous casting method to produce single [...]

Orientierung von Siliziumkristallen

The Silicon crystal orientations that we often hear are <100>, <110> and <111>(shown as Fig. 1), respectively indicating a crystallographic family. The single crystal silicon structure belongs to cubic crystals, and the <100> crystal orientation family represents six crystal orientations: [100], [010], [001], [100], [0-10], and [00-1]. Therefore, we rarely hear [...]

Silizium-Einzelelektronentransistor

Single electron transistor (SET) is an important discovery in microelectronics science. Due to the ability to control the tunneling process of a single electron in a micro tunnel junction system, multiple functional devices can be designed using it. In modern submicron devices, the limiting factor for device operation speed is [...]

Speicherleistungsanalyse der InSb-Verbindung

Indium antimonide (InSb) compound semiconductor, as a direct bandgap semiconductor material, has low electron effective mass, high mobility, and narrow bandgap width. At low temperatures, InSb compound has a high absorption coefficient for infrared light, with a quantum efficiency greater than or equal to 80%. In terms of mid infrared [...]

Statischer SiC-Induktionstransistor (SIT) *S

Static induction transistor (SIT) is a type of junction field-effect transistor. It is a unipolar voltage control device developed on the basis of ordinary junction field-effect transistors, with three electrodes: active, gate, and drain. Its source drain current is controlled by an external vertical electric field on the gate. SIT transistor is [...]

Silikonfilter

With the development of miniaturization and single-chip devices, the integration of active and passive circuits is the trend. Conventional filters have become the bottleneck for miniaturization and single-chip of microwave and millimeter wave devices due to their large size (especially in the millimeter wave frequency band), and only chip [...]

InGaAs/InP MUTC-Fotodetektor (MUTC-PD) Wafer

Terahertz (THz) wave generation technology is widely used in fields such as terahertz sensing, safety imaging, non-destructive material testing, and high-speed terahertz wireless data communication. Optical heterodyne is a method of achieving continuous tunable terahertz wave emission by mixing beat frequency signals of two laser modes with different wavelengths [...]

3C SiC-Wafer

Compared to 4H-SiC, although the bandgap of 3C silicon carbide (3C SiC) is lower, its carrier mobility, thermal conductivity, and mechanical properties are better than those of 4H-SiC. Moreover, the defect density at the interface between the insulating oxide gate and 3C-SiC is lower, which is more conducive to manufacturing high-voltage, [...]

Photonics Epitaxial Wafers

With the continuous evolution of optical telecommunication and opto-electronics device applications towards high speed and high performance, we are closely following market demand in photonics epitaxial wafers for high-speed and high-end optoelectronic applications. PAM-XIAMEN can provide a series of compound semiconductor based photonics epitaxial wafers, which can be used as key optoelectronic chip [...]

SiC BJT Wafer *S

SiC wafer can be used to manufacture BJT (bipolar junction transistor) devices with low conduction resistance and high blocking voltage up to tens of kilovolts. For applications with a blocking voltage of 4.5kV and higher, bipolar SiC power devices will have more practical application value than unipolar SiC power devices. Compared with most field-effect [...]
